Two types of substrates are investigated which bear two acyl groups ortho to each other on a benzene ring. [ABSTRACT FROM AUTHOR]

The reaction of dithioacetals (I) with nitriles (II) followed by a zinc-mediated one-pot reaction of the isolable intermediate (V) leads to 5-ethylthiopyrroles (III), whilst the copper-mediated reaction of the intermediate (V) affords 4-ethylthiocarbonylpyrroles (IV) via a second isolable intermediate (VI).

Michael addition of N-(p-chlorobenzylidene)glycine methyl ester (II) with various enones is combined with cyclization during the workup on silica gel column chromatography to give polysubstituted pyrrolines (III)/(IV), (VI)/(VII) and (IX)/(X) as diastereomeric mixtures. [ABSTRACT FROM AUTHOR]

The article presents a chemical reaction of direct synthesis of the pyrrole [3,4-c] quinolines by using the domino reaction of tosylmethyl isocyanides and aminochalcones.

A series of trifluoromethylated 1,3-dien-3-ols (IV) are synthesized by regiospecific addition of the Ruppert-Prakash reagent to divinyl ketones (I) and transformed into trifluoromethylated cyclopentadienes (V), norbornenes (VII), and fulvenes (IX). [ABSTRACT FROM AUTHOR]

The regioselective one-pot [3 + 2]-cycloaddition/iodocyclization cascade reaction of alkyne-tethered cinnamates/chalcones and toluenesulfonylmethyl isocyanide (TosMIC) shows a dedicated solvent dependence. [ABSTRACT FROM AUTHOR]

The base-promoted reaction of cyclic enediones with isocyanides (II) leads to 7- and 8-membered-ring fused pyrroles (III) in moderate yields. [ABSTRACT FROM AUTHOR]

The article presents chemical equations related to the article "Facile [7C + 1C] Annulation as an Efficient Route to Tricyclic Indolizidine Alkaloids" by X. Liu, L. Zhang, L. Pan and others, published in the "Angewandte Chemie International Edition" in 2013.

A novel strategy for the synthesis of title compounds (III)/(IV) and (VI)/(VII) from alkenoylacetamides (I) and (V) and isonitrile (II) is described. [ABSTRACT FROM AUTHOR]
