摘要:
A scalable synthesis of isoflavones taking advantage of the Suzuki-Miyaura reaction catalyzed by Pd(0)/C is described. The approach developed has been extended to the total synthesis of 7-O-geranylformononetin, griffonianone D, and conrauinone D, which did not display cytotoxicity against human HeLa carcinoma cells. In addition, this study established unambiguously the absolute configuration of natural griffonianone D. (c) 2007 Elsevier Ltd. All rights reserved.
