A consecutive approach towards the stereoselective synthesis of trisubstituted THF domains
摘要:
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.

8–14 derived from their respective glycals with Sharpless, m-CPBA and Camp’s reagents was carried out in order to obtain 2,3-epoxy alcohols keeping in view the versatility of these synthons in synthetic chemistry for the preparation of various molecules of biological importance by suitable chemical transformations. During the course of this study, the Sharpless asymmetric epoxidation reaction was found
