Reactions with Aziridines; 34. γ-Amidoketones by Amidoethylation of Ketones
Stamm, Helmut,Weiss, Rainer
, p. 392 - 395 (2007/10/02)
Sodium enolates of ketones react with 1-acyl-, 1-aminocarbonyl, and 1-alkoxycarbonylaziridines to give γ-amidoketones .Twofold amidoethylation in α,α- or α,α'-position can usually be suppressed by using excess enolate, exept for the amidoethylation of 1-indanone.
