Isomerization, autoxidation and epimerization for the introduction of C-1 to C-5 functionality into the taxane ABC ring system
摘要:
Treatment of 2-ketotax-3-enes with r-BuOK/t-BuOH/THF/65 degrees C results in isomerization of the double bond into the 4,5-position and a trans-B/C ring fusion. Subsequent exposure to t-BuOK/THF/O-2/P(OEt)(3) introduces the C-1-hydroxyl group. Copyright (C) 1996 Elsevier Science Ltd
