Synthesis of Polyquinane Natural Products: An Update.
Journal ArticleDOI
An improved preparation of vinyl iodides
TL;DR: In this article, it was shown that the oxidation of ketone hydrazones by iodine in the presence of a base to furnish vinyl iodides has been improved by three factors: absence of water, the use of strong guanidine bases and inverse addition.
Journal ArticleDOI
Practical procedures for the preparation of N-tert-butyldimethylsilylhydrazones and their use in modified Wolff-Kishner reductions and in the synthesis of vinyl halides and gem-dihalides.
TL;DR: Aliphatic and aromatic ketones and aldehydes are shown to undergo highly efficient coupling to form the corresponding TBSH derivatives when combined with equimolar amounts of 1,2-bis(tert-butyldimethylsilyl)hydrazine (BTBSH) and a catalytic quantity of scandium trifluoromethanesulfonate (typically, 0.01 mol %).
Journal ArticleDOI
A novel and convenient method for palladium-catalysed alkoxycarbonylation of aryl and vinyl halides using HCO2R/NaOR system
TL;DR: Aryl iodides, vinyl bromides and tricarbonyl(chloroarene)chromium complexes react under mild conditions with sodium alkoxides and alkyl formates as source of carbon monoxide in the presence of dichlorobis(triphenylphosphine)-palladium as catalyst to give the corresponding carboxylic esters in high yields.

Organocopper Reagents: Substitution, Conjugate Addition, Carbo/Metallocupration, and Other Reactions
TL;DR: In this paper, two reviews were contributed to the Organic Reactions series covering substitution and conjugate addition reactions in organocopper chemistry, and many solutions to this problem now exist.
