1,4-Addition of Diisobutylaluminium Benzenetellurolate to α,β-Unsaturated Carbonyl Compounds and Aldol Reaction of Resulting Aluminium Enolates

Abstract

Abstract Diisobutylaluminium benzenetellurolate, prepared from diphenyl ditelluride and diisobutylaluminium hydride, easily added to α,β-unsaturated carbonyl compounds in 1,4-fashion to give β-phenyltelluro carbonyl compounds. The intermediate aluminium enolates reacted with aldehydes to give aldol adducts. Subsequent telluroxide elimination resulted in the formation of α-substituted α,β-unsaturated carbonyl compounds.
