OPTICAL ENANTIOMERS OF PHENYRAMIDOL AND PROCESS FOR CHIRAL SYNTHESIS

摘要

The present invention discloses optically pure (R) and (S) Phenyramidol enantiomers and their pharmaceutically acceptable salts, a process for synthesizing such enantiomers by means of a styrene oxide based synthesis, and also a clinical evaluation of (R) and (S) enantiomers of Phenyramidol, their salts and compositions thereof for enhanced/newer therapeutic benefits.
