Stereospecific synthesis of 7-deoxy-6-hydroxy paclitaxel
摘要:
The synthetic transposition of the 7-hydroxyl group of paclitaxel to the 6-position is described. The route presented prepares both the 6-alpha- and beta-isomers stereospecifically. The key step of this transposition involves the stereoselective reduction of the 6,7-alpha-thiocarbonate using tributylgermanium hydride. (C) 1999 Elsevier Science Ltd. All rights reserved.
