Abstract

The first catalytic enantioselective alpha-sulfenylation of deconjugated butyrolactams has been developed using dimeric cinchona alkaloids as catalysts in a water-enriched reaction medium. Highly substituted and densely functionalized gamma-lactams, bearing a quaternary stereogenic center, are produced with up to 99.5 : 0.5 er. The applicability of the same catalyst system for the enantioselective alpha-selenylation and formal vinylogous.-hydroxylation of deconjugated butyrolactam has also been described.
