  Enantioselective Synthesis of Conformationally Restricted Analogs of NMDA:  cis- and trans-Piperidine-2,3-dicarboxylic Acids and Methylated Derivatives

  摘要：

  Various enantiopure stereoisomeric cyclic amino diacids belonging to the 2,3-piperidinedicarboxylic acid series mere obtained via an aza-annulation reaction between enamino esters and acryloyl, methacryloyl, or crotonyl chloride. Enantioselective syntheses of these conformationnally restricted analogs of N-methyl-D-aspartic acid were realized owing to a chiral induction originated from (2S)-2-phenylglycinol. New information about the mechanism of the aza-annulation process is inferred from AM1 calculations which were performed in order to explain the steroselectivity displayed during the formation of the C-4 stereocenter In compound 4.
