Abstract

The novel pyrrolidine-sulfonamide I has been prepared and used successfully to catalyze Mannich-type reactions between ketones and α-imino esters. The process is used to efficiently synthesize functionalized α-amino acid derivatives with excellent levels of regio-, diastereo-, and enantio-selectivity.
