General description
Asymmetric addition of (triisopropylsilyl)acetylene to α,β,γ,δ-unsaturated carbonyl compounds in the presence of a cobalt/Duphos catalyst is reported. A Sonogashira coupling reaction between 1-bromo-3-iodo-5-tertbutylbenzene and (triisopropylsilyl)acetylene is reported.
Application
(Triisopropylsilyl)acetylene may be used as reagent for the rhodium-catalyzed asymmetric alkynylation of various α,β-unsaturated ketones. It may be used as reagent in the enantioselective synthesis of β-alkynylated nitroalkanes.
