Abstract
A concise synthetic approach to 4-trifluoromethyl steroids, a novel cl ass of steroid 5 alpha-reductase inhibitors, is described. Direct trif luoromethylation of steroid olefinic bromide with methyl fluorosulfony l-difluoroacetate was used as a key step in the synthesis. The compoun d 4 exhibited highly inhibitory activity than Finasteride in in vitro assay. (C) 1997 Elsevier Science Ltd.
