Abstract
The titled cyclization induced by Sn-Li transmetallation of the enanti o-defined stannanes is shown to proceed with complete retention of con figuration at the Li-bearing sp(3)-carbon to afford the enantio-enrich ed alpha,beta-disubstituted tetrahydrofurans. (C) 1997 Elsevier Scienc e Ltd.
