Abstract

The titled cyclization, when performed in the presence of lithium chloride, afforded an improved yield of the enantio-enriched 2,3-trans- disubstituted tetrahydrofuran derivative in high diastereoselectivity, whereas a similar cyclization in the presence of zinc bromide gave the 2,3- cis isomer as the major product in lower enantiopurity.
