Resumen

An efficient regio- and stereocontrolled methodology for the alkylative bridge

cleavage of oxabicyclic vinyl sulfones is described. A range of 7 -oxabicyclic[2.2.1. ]heptenyl

and 8-oxabicyclic [3.2.1.]octenyl sulfones has been found to undergo an overall syn

S~' opening when treated with a wide variety of organolithium reagents and lithium

aluminum hydride. In this manner, higWy functionalized cyclohexenyl and cycloheptenyl

sulfones, versatile synthetic intermediates, are now available in high yields. The

complete stereoselectivity encountered in the exo conjugate addition may be explained

by chelation of the organometallic reagent with the oxygen bridge and steric factors.

Furthermore, less-strained substrates allow for complete control of the addition and

elimination stages.
