ENANTIOMERS OF 1-[(4-CHLOROPHENYL)-PHENYLMETHYL]-4-[(4-METHYLPHENYL)SULFONYL]PIPERAZINE

摘要

Levorotatory and dextrorotatory enantiomers of 1-¢(4-chlorophenyl)phenylmethyl!-4-¢(4-methylphenyl)sulfonyl!piperazine of the formula <IMG> (I) their preparation and use for the preparation of substantially optically pure enantiomers of 1-¢(4-chlorophenyl)phenylmethyl!piperazine, which are themselves valuable intermediate products for the preparation of optically active therapeutic compounds having a very high degree of optical purity.
