A practical synthesis of 3-substituted delta 3,5(6)-steroids as new potential 5 alpha-reductase inhibitor

Bioorg Med Chem Lett. 1998 Aug 4;8(15):1949-52. doi: 10.1016/s0960-894x(98)00339-4.

Abstract

A new and practical synthetic approach to 3-substituted delta 3,5(6)-Steroids, as potential 5 alpha-reductase inhibitor, is described. The key step involves Pd-catalyzed coupling reaction of steroid 3-enol 5H-3-oxo-octafluoropentanosulfonates. 3-Phenylacetylenyl substituted delta 3,5(6)-steroid 3g and 3-phosphate substituted delta 3,5(6)-steroid 3f in our synthesized compounds exhibited high 5 alpha-reductase inhibitory activity in vitro assay.
