Synergistic methodologies for the synthesis of 3-aroyl-2- arylbenzo[b]thiophene-based selective estrogen receptor modulators. Two concise syntheses of raloxifene

Bradley, David A.,Godfrey, Alexander G.,Schmid, Christopher R.

, p. 5155 - 5159 (2007/10/03)

Difunctionalized benzo[b]thiophene intermediates are prepared which allow fully independent elaboration of the 2-aryl position or the tether position of benzo[b]thiophene-based selective estrogen receptor modulators (SERMs). Two concise syntheses of the SERM raloxifene (Evista) are presented.
