The chiral binaphthol-catalyzed enantioselective conjugate addition of alkynyl trifluoroborates to cyclic N-sulfonyl ketimines is reported, providing β-alkynyl imines bearing a propargylic ...

An electrochemical method was developed to convert α,β-unsaturated aldehydes into carboxylic acid derivatives via cyanosilylation, isomerization, and nucleophilic addition. This reaction is more ...
