摘要

Abstract Diels-Alder reaction of cyclopentadiene and methyl N-carbobenzyloxy-2- iminoacetate generated in situ from methyl 2-chloro-N-carbobenzyloxyglycinate by triethylamine gave the N-carbobenzyloxy unsaturated bicyclic proline ester. This was converted in two steps to 2-azabicylo [2.2. 1] heptane-3-carboxylic acid. In contrast to N- carbobenzyloxy-L-proline methyl ester, the corresponding bicyclic proline ester was ...
