Review: [recent advances in gold-catalyzed selective cyclopropanation reactions; 76 refs. [ABSTRACT FROM AUTHOR]

Several benzopolycyclic compounds are formed from 2-(2-alkynylarylidene)-1,3-dicarbonyl compounds by Lewis-acid catalysis. [ABSTRACT FROM AUTHOR]

Review: [32 refs. [ABSTRACT FROM AUTHOR]

The article presents diagrams of spirocyclic diketones featuring gold or broensted acid relay catalysis are presented.

The reaction proceeds with excellent diastereoselectivity and is effective only starting from the (E)-substrates. [ABSTRACT FROM AUTHOR]

A new and efficient strategy for enynes cyclization catalyzed by triflic acid is disclosed. [ABSTRACT FROM AUTHOR]

A diagram is presented which shows the sterospecific (4+3)-cycloaddition reaction which is gold catalyzed of the ketones 1-(Alk-1-ynyl) cyclopropyl with nitrones and presents the modular entry to 5,7-fused bicyclic furo(3,4-d)(1,2) oxazepines that enantioenriched.

Indole and pyrrole oxiranes are converted to oxazines in the presence of scandium triflate in high yields. [ABSTRACT FROM AUTHOR]

A wide range of oxazolidines is prepared in high yields and mostly good diastereoselectivities. [ABSTRACT FROM AUTHOR]

An alternative route for the synthesis of the title compounds by using oxiranes instead of aldehydes is presented via sequential Meinwald rearrangement and cycloaddition. [ABSTRACT FROM AUTHOR]

A novel and efficient gold-catalyzed cascade C-H functionalization/5-endo-dig cyclization of o-alkynylaryl α-diazoesters with electron-rich aromatic compounds is established. [ABSTRACT FROM AUTHOR]

An abstract of the study "Enantioselective Gold-Catalyzed Intermolecular [2 + 2]-Cycloadditions of 3-Styrylindoles With N-Allenyl Oxazolidinone" by H. Hu and colleagues is presented.

The article presents chemical equations related to the article "Gold-Catalyzed Construction of Two Adjacent Quaternary Stereocenters via Sequential C-H Functionalization and Aldol Annulation" by Z. Yu and others, published in journal "Chemical Communication" in 2016.

The title method provides fused azepine derivatives having multiple contiguous stereogenic centers. [ABSTRACT FROM AUTHOR]

The title reaction is optimized with respect to the BINOL-derived phosphoramidite catalyst to give fully substituted furans with good diastereo- and generally excellent enantioselectivity. [ABSTRACT FROM AUTHOR]

When the substituents on the nitrogen of indoles are hydrogen or electron-donating groups, such as methyl [e.g. (I)], benzyl, allyl groups, [2 + 2]-cycloaddition takes place to give the products [e.g. (III)] as (Z)-isomers with excellent yields and enantioselectivities. [ABSTRACT FROM AUTHOR]

It is demonstrated, that the stereochemical information of vinyl-alkyne substrates containing a chiral aziridine substituent can be transferred to fused dihydroazepine derivatives by a Rh-catalyzed formal [5 + 2] cyclization. [ABSTRACT FROM AUTHOR]

The article reports on Gold(I)-Catalyzed Highly Diastereo- and Enantioselective Alkyne Oxidation/Cyclopropanation of 1,6-Enynes.

Intermediary o-quinodimethanes are trapped with alkenes and alkynes, respectively, to provide highly functionalized furan derivatives. [ABSTRACT FROM AUTHOR]

The new title ligands can be easily prepared from inexpensive and commercially available starting materials. [ABSTRACT FROM AUTHOR]

Novel divergent cyclizations of perfluoroalkylated and alkynyl-substituted hydroxylamines are developed. [ABSTRACT FROM AUTHOR]

A wide range of dihydrobenzofurans and isobenzofurans as well as heterocyclic analogues thereof are prepared via gold-catalyzed 1,2- or 1,2′-alkyl migration processes. [ABSTRACT FROM AUTHOR]
