Abstract

The organolithium mediated bridge opening of unsymmetrically substituted 8-oxabicyclo[3.2.1]octene derivatives 6, 7, proceeds with completeregio- and stereoselectivity to afford highly functionalized hydroxycycloheptenyl sulfones 10, 12 in high yields. It was also found possible to control the conjugate addition/beta-elimination sequence towards the synthesis of adducts 8,9, 11.
