摘要:
Alkoxymethyl groups at the C-5 allylic position of 1,6-dienols have been found to accelerate RCM reactions significantly with the Grubbs' catalyst PhCH=Ru(PCY3)(2)Cl-2. This phenomenon has been used for direct access to highly substituted cyclopentenols, potential intermediates in the synthesis of carbovir, abacavir and BCA. (C) 2004 Elsevier Ltd.
