A novel Michael-initiated ring closure reacton involving allylic chlorosulfone (2) and γ-alkoxy-α,β-ynoates to afford 4- methylenecyclopentenecarboxylates is reported, while with γ-alkylynoates no reaction occurred. With chiral phenyl ynoates 4, the reaction proceeds by 1,3-asymmetric induction and leads further to a nonracemic annulated α,β- butenolide (7). (C) 2000 Elsevier Science Ltd.
