Isopropenyl phenyl sulfone

Bicycloannelation.3 The 2 -enolatC (1) of isophoronc reacts with phenyl vinyl sulfone in THF containing 4 equivalents of HMPT (essential) to give the bicycloannelation product 2 in 38% yield. The yield is considerably greater than that obtained from the same reaction using vinyltriphenylphosphonium bromide. Reaction of 1 with isopropenyl phenyl sulfone gives 3 in 21% yield. [Pg.316]
