Semisynthesis of D-ring modified taxoids: novel thia derivatives of docetaxel

J Org Chem. 2001 Jul 27;66(15):5058-65. doi: 10.1021/jo015539+.

Abstract

Two novel 5(20)-thia analogues of docetaxel have been synthesized from 10-deacetylbaccatin III or taxine B and isotaxine B. The key step of these syntheses is the concomitant thietane ring formation and acetylation of the tertiary alcohol at C-4. Both compounds are less cytotoxic than docetaxel but have divergent activity on microtubule disassembly.
