The influence of the base, LDA or LiHMDS, used for the formation of the glycine enolates, was of great importance for the anti-/syn-diastereoselectivity of the Mannich-type reaction. The gamma-chloro-alpha,beta-diamino acid derivatives proved to be excellent building blocks for ring closure towards optically pure anti-and syn-beta,gamma-aziridino-alpha-amino esters, and subsequent ring transformation into trans-3-aminoazetidine-2-carboxylic acid derivatives and alpha,beta-diamino-gamma-butyrolactones.
