Remarkably Selective Reduction of the α,β-Carbon−Carbon Double Bond in Highly Activated α,β,γ,δ-Unsaturated Alkenes by the InCl3−NaBH4 Reagent System
摘要:
A combination of sodium borohydride and a catalytic amount of indium(III) chloride in acetonitrile reduces exclusively the alpha,beta-carbon-carbon double bond in alpha,beta,gamma,delta-unsaturated diaryl ketones, dicarboxylic ester, cyano-ester, and dicyano compounds.
The first examples of palladium-catalyzed allylic C–H oxidative allylation of sulfoxonium ylides to afford the corresponding conjugateddienones with moderate to good yields have been established. The features of this novel conversion include mild reaction conditions, wide substrate scope, and excellent regioselectivity.
