摘要
The beta-amino carboxylic acid moiety is a key feature of numerous important biologically active compounds. We describe a syn-selective direct Mannich addition reaction that uses alpha-iodo thioesters and sulfonyl imines and produces beta-amino thioesters. Enolate formation is achieved by reductive soft enolization. The products of the reaction provide straightforward access to biologically important beta-lactams through a variety of known reactions.
