SYNTHESIS OF CHIRALLY PURIFIED SUBSTITUTED BENZOTHIAZOLE DIAMINES

摘要

Methods for preparing chirally purified substituted 4,5,6,7-tetrahydro-benzotiazole diamines such as, for example, (6R)2-amino-4,5,6,7-tetrahydro-6-(propylamino)benzothiazole and purifying a dominant enantiomer of substituted 4,5,6,7-tetrahydro-benzotiazole diamines from entantiomerically enriched mixtures of substituted 4,5,6,7-tetrahydro-benzotiazole diamines are provided herein.
