ChemInform Abstract: Direct Carbon—Carbon Bond Formation via Reductive Soft Enolization: A syn‐Selective Mannich Addition of α‐Iodo Thioesters.

Abstract

The β-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 α-iodo thioesters and sulfonyl imines and produces β-amino thioesters. Enolate formation is achieved by reductive soft enolization. The products of the reaction provide straightforward access to biologically important β-lactams through a variety of known reactions.
