Abstract

Aldol products from a non-aldol reaction: A one-pot protocol effects hydrosilylation of propargyl alcohols and subsequent oxidative cleavage to yield β-hydroxy ketones in a chemo-, regio-, and enantioselective fashion. Further structural elaboration of the intermediate γ-hydroxyvinylsilane is possible before the carbonyl group is unmasked (see scheme).
