General strategy towards chiral methylene bis-pyrans: synthesis of the C2–C16 fragment of phorboxazole A
摘要:
A chiral methylene bis-pyran fragment was synthesized by making efficient use of an oxy-anion intramolecular Michael addition, Brown's asymmetric allylation and Grubb's ring closing metathesis reactions in a stereoselective manner. (c) 2005 Elsevier Ltd. All rights reserved.
