Abstract

Abstract An efficient methodology for the preparation of the α-tetrasubstituted proline analog (S, S, S)-2-methyloctahydroindole-2-carboxylic acid,(S, S, S)-(αMe) Oic, and its enantiomer,(R, R, R)-(αMe) Oic, has been developed. Starting from easily available substrates and through simple transformations, a racemic precursor has been synthesized in excellent yield and further subjected to HPLC resolution using a cellulose-derived chiral ...
