Synthesis of 4-Substituted Prolines as Conformationally Constrained Amino Acid Analogues

Anionic substitution of N-(9-(9-phenylfluorenyl))-protected glutamic acid esters proceeds without loss of optical integrity to give 4-substituted glutamic acid derivatives.The 4-methyl, propyl, cyanomethyl, and phenyl analogues have thus been prepared.Pri
