Abstract
Highly electron-deficient vinyl and ethynylcyclo-propane 1,1-dicarboxy lic esters conveniently synthesized by the reaction of allylic diisobu tyltelluronium ylides with alkylidene or arylmethy-lidene malonic este rs with high yields and high stereoselectivity. The effects of the rea ction media and bases used to produce the ylides on the stereoselectiv ity are studied. Copyright (C) 1996 Elsevier Science Ltd
