Abstract

A catalyst-free three-component synthesis of α-aryl- and α-alkenylglycine derivatives starting from glyoxylic acid, sulfonamides, and aryl- or alkenylboronic acids is described. This operationally simple method tolerates a broad range of functional groups and enables the generation of a wide array of α-amino acids. Sulfonamides were utilized as amine component in the classic Petasis reaction for the first time.
