Abstract

Yarrow, Achillea millefolium L., is one of the commonest weeds of the Compositae family. Cases of allergic contact dermatitis have been described since 1899. Although 10 sesquiterpene lactones (SL) and 3 polyines have previously been identified, the sensitizers of yarrow have escaped detection. A reinvestigation of short ether extracts of yarrow revealed the presence of 5 unsaturated hitherto unknown guaianolides of peroxide character. The main SL, identified as a strong sensitizer in guinea pig sensitization experiments, was named alpha-peroxyachifolid. The minor SL also contribute marginally to the sensitizing capacity, while other known yarrow constituents like dehydromatricaria ester and pontica epoxide appear to play no role. A 5-year follow-up (1985-1990) of Compositae-sensitive patients showed that more than 50% reacted when tested with a short ether extract of yarrow. Exacerbation of the patch test sites by irradiation with UV light was never observed.

Abstract

Fur ein Bestrahlungsprodukt des Nardosinons (1), das auch durch Umsetzung von Isonardosinon (4) mit Wasserstoffperoxid in alkalischer Losung gebildet wird, wurde schon fruher die Struktur eines Hydroxyketons vorgeschlagen, das mit einem viergliedrigen Halbketal im Gleichgewicht 2a,b steht2). Nach erneuter Uberprufung konnte auf Grund chemischer Reaktionen und spektroskopischer Daten die Struktur eines Diepoxyketons festgelegt werden, das mit einem sechsgliedrigen cyclischen Halbketal 7a,b im Gleichgewicht steht. Structure of an Irradiation Product of Nardosinone For an irradiation product of nardosinone (1), which is also formed in the reaction of isonardosinone (4) with hydrogen peroxide in alkaline solution, the structure of a hydroxy ketone, which is in equilibrium with a four-membered cyclic hemiacetal (2a,b) was proposed2). Based on chemical reactions and spectroscopic data, the structure of a diepoxy ketone, which is in equilibrium with a six-membered cyclic hemiacetal 7a,b is now suggested.

Abstract

Quantitative extraction studies from urine were carried out by addition of cocaine, benzoylecgonine, ecgonine methyl ester and ecgonine to urine samples. After hydrolysis to ecgonine the compounds were analyzed together. Ecgonine was isolated by a cation-exchange resin and purified by an anion-exchange resin. The quantitative determination was performed by GC after silylation with MSTFA. The recovery was 77% at a concentration of 150 μg ecgonine/ml urine. A qualitative determination of ecgonine by GC/MS was possible up to the detection limit of 20 ng/ ml. The method can be applied for the detection of cocaine abuse.

Abstract

From the air dried root of Melia azedarach L. (Meliaceae) the following constituents were isolated: 24–methylene cycloartanone, cycloeucalenone, 4–stigmasten–3–one and 4–campesten–3–one, 24–methylenecycloartanol, triacontanol–(1), cycloeucalenol, β–sitosterol, β–sitosterol–β–D–glucoside, vanillic aldehyde, trans–cinnamic acid and vanillic acid. In the fruits, besides known constituents one compound could be isolated for which we propose the structure of 21,23 :24,25–diepoxi–tirucall–7–en–21–ol. The structure of a protolimonoid C30H46O5 could not be elucidated. In addition, besides triacontanol, vanillic aldehyde, trans–cinnamic acid, 3β–hydroxy–5–stigmasten–7–one and 3β–hydroxy–5–campesten–7–one, the same cyclolanostane derivatives as in the root were identified.

Dieses stellt das unter alkalischen Bedingungen uberraschende Produkt einer Baeyer-Villiger Oxidation dar. Erst durch Variation der Temperatur von +15° auf −15° und des Molverhaltnisses wurde das Epoxynardofuran 2 erhalten, das Zwischenprodukt fur die Bildung von 3 ist. Unusual Baeyer-Villiger Oxidation with Alkaline Hydrogen Peroxide Solution The reaction of nardofuran (1) with alkaline hydrogen peroxide did not provide the expected epoxyketone 2, but the epoxylactone 3. Under the conditions applied this is a rare Baeyer-Villiger oxidation product. By lowering the temperature from +15°C to −15°C and by altering the molar ratio of the reactants, epoxynardofuran 2 was obtained, which is an intermediate in teh formation of 3.

Das Sesquiterpen-Peroxid Nardosinon (8) bildet mit POCl3/Pyridin das Chlor-Derivat 1 und unter Fragmentierung des Isopropylrestes die Enolchloride 7 und 10. Mit H2SO4 kommt es ebenfalls zur Fragmentierung der Isopropyl-Gruppe unter Bildung von 9 und 11 bzw. zur Umlagerung des Nardosinon-Gerustes zu 12. Unter gleichen Reaktionsbedingungen werden aus dem Epoxi-Keton Isonardosinon (2) auser 12 nur Derivate mit dem unveranderten Nardosinon-Gerust erhalten. Reactions of Nardosinone and Isonardosinone with Acidic Reagents The reaction of the sesquiterpene peroxide nardosinone (8) with POCl3/pyridine leads to the chloro derivative 1 and, by fragmentation of the isopropyl group, to the enol chlorides 7 and 10. Treatment with H2SO4 causes fragmentation of the isopropyl group giving 9 and 11 or leads to a rearrangement of the nardosinone skeleton that yields 12. Under the same conditions, the epoxy ketone isonardosinone (2) is converted to 12 and to derivatives which contain the unchanged nardosinone skeleton.

Abstract

Fur spiro- α-Methylen- γ-butyrolactone, welche durch Reformatsky-Reaktion aus 2-Alkyl-cyclohexanonen und α-Brommethylacrylsaureethylester hergestellt wurden, wird eine Beziehung zwischen der chemischen Verschiebung der C-Atome 4,5 und 9 im 13C-NMR-Spektrum und der konformativen Anordnung des Lactonsauerstoffs abgeleitet. Sie wird durch CD-Messung am Pyrazolin-Derivat eines der Lactone bestatigt. Aus der Strukturzuordnung der Reaktionsprodukte folgt, das bei der Synthese die trans-Addition der metallorganischen Verbindung bezuglich des Substituenten in 2-Stellung begunstigt ist. Stereochemistry of the Reformatsky Reaction of 2-Alkylcyclohexanones with Ethyl α-(Bromomethyl)acrylate A relation between the chemical shifts of the 13C-NMR signals of the carbon atoms 4, 5 and 9 and the conformation of the lactone oxygen was found for spiro-α-methylene-γ-butyrolactones prepared by the Reformatsky reaction of 2-alkylcyclohexanones with ethyl α-(bromomethyl)acrylate. It was confirmed by CD measurements on the pyrazoline derivative of one of the lactones. From the structures of the reaction products it was deduced, that trans addition (relative to the substituent at position 2) of the organometallic reagent is prefered.

Abstract

Bei der jodometrischen Gehaltsbestimmung des Ascaridols (10) nach DAB 7 entstehen mindestens 15 Reaktionsprodukte, von denen 7 Substanzen schon durch Umsetzung von etwa 5–10% 10 mit Saure gebildet werden (1a, b, 2a, b, 3, 4, 14). Die Reduktion von 10 durch Jodid verlauft, wie schon fruher von Bohme u. Mitarb. diskutiert, zu cis-2-p-Menthen-diol-1,4 (11), das anschliesend mit Saure in die isomeren Menthendiole 5, 6 und 8 und ihre Mono-Acetate ubergeht bzw. mit Jodid in einer reduktiven 1,4-Eliminierung unter Jod-Ausscheidung 1,3-p-Menthadien (12) bildet. Die Diole 5, 6 und 8 werden zu p-Cymol (13) dehydratisiert, welches durch Oxidation teilweise 8-Hydroxy-p-cymol (14) bildet. 12 wird zu 3-p-Menthen-8-ol (15) oxidiert oder reagiert mit 14 zu den dimeren Verbindungen 16, 17 und 18. On the Products of the Iodometric Assay of Ascaridol At least 15 products are formed in the iodometric assay of ascaridol (10) when carried out according to DAB 7. Seven of these products (1a, b, 2a, b, 3, 4, 14) arise from the reaction of 10 with hydrochloric acid. As reported earlier by Bohme et al., the reduction of 10 by iodide gives cis-2-p-menthene diol (11), which either is converted by acid into the isomeric menthenediols 5, 6 and 8 and their monoacetates or reacts with iodide by a reductive 1,4-elimination to form 1,3-p-menthadiene (12). The diols 5, 6 and 8 are dehydrated to p-cymol, which is oxidized in part to 8-hydroxy-p-cymol (14). Compound 12 is oxidized to 3-p-menthene-8-ol or forms the dimeric compounds 16, 17 and 18 by reaction with 14.

Formation of 1,2-Dioxolanes from Cyclopropanes The already known carenols 5 and 7 are obtained by stereoselective oxirane cleavage of (1S,3S,4R,6R)-( + )-3α,4α-epoxycarane (4). Autoxidation of the ketone 8, derived from 7, failed to give any 1,2-dioxolane derivatives. 5 is converted to the hydroperoxide 9 by cyclopropane opening using 70% hydrogen peroxide solution. Cyclization of 9 with lead tetraacetate affords the dioxolane 10.

Abstract

Die Rontgenstrukturanalyse zeigt, das im Nardosinon (1) der 1,2-Dioxolan-Ring in cis-Stellung steht. Die Bildung des Nardofurans (3) aus Isonardosinon (2) verlauft daher unter Retention der Konfiguration an C-4. On the Configuration of Nardosinone X-ray analysis of nardosinone (1) shows cis position of the 1,2-dioxolane ring. Therefore, the formation of nardofuran (3) from isonardosinone (2) takes place by retention of the configuration at C-4.

Abstract

A new instable aristolane type sesquiterpene ketone, gansongone ( 1), was isolated from the fresh underground parts of NARDOSTACHYS CHINESIS Batalin (Valerianaceae), growing in the province Sichuan (China). The structure of 1 was elucidated by spectroscopic and chemical methods. The structure of the corresponding alcohol 2, which was also found in N. CHINENSIS and formerly regarded as 9-aristolene-1alpha-ol ( 5) has to be revised to l(10)-aristolene-9beta-ol ( 2) from results of 2D-NMR-spectroscopy and oxidation to 1. Besides 1 and 2, the following compounds have been identified in the ethanol extract of the fresh plant material of N. CHINENSIS: nardosinone, nardosinondiol, deoxonarchinol A, beta-sitosterol, oleanolic acid, ethyl beta- D-glucopyranoside.
