A highly efficient, consecutive approach for the construction of synthetically valued, enantiomerically pure, trisubstituted THF domains 3-10 in a stereoselective manner starting from glycal derived allylic alcohols 1a-1d under Sharpless asymmetric epoxidation (SAE) conditions is reported. The reaction involves the intramolecular asymmetric ring opening (ARO) of in situ formed enantiopure 2,3-epoxy alcohols followed by protection of the diol. (c) 2006 Elsevier Ltd. All rights reserved.
