Enantioselective synthesis of conformationally restricted analogs of NMDA: cis- and trans-Piperidine-2,3-dicarboxylic acids and methylated derivatives

Various enantiopure stereoisomeric cyclic amino diacids belonging to the 2,3-piperidinedicarboxylic acid series were obtained via an aza-annulation reaction between enamino esters and acryloyl, methacryloyl, or crotonyl chloride. Enantioselective synthese
