A two-step method for the preparation of homochiral cathinones
摘要:
A simple method for the preparation of homochiral ring-substituted 1-aryl-2-aminopropanones 2 ('cathinones') is described, involving initial Friedel-Crafts acylation of aromatics with (S)- or (R)-N-trifluoroacetylalanyl chloride, followed by acid hydrolysis of the intermediate trifluoroacetamido intermediates 1. for which X-ray diffraction analysis confirmed the structures.
