Abstract

N-Alkylation of N-allyl α-amino esters and [2, 3]-Stevens rearrangement occur in one pot on warming in the solvent DMF, with the bases K2CO3 and DBU; this in situ formation of the quaternary ammonium salts and rearrangement of the subsequent ylides gives N, N- dialkylated allyl glycine derivatives.
