An efficient method for synthesis of polysubstituted cyclobutenones, which are not readily available from traditional methods due to the intrinsic ring strain, is described. The reaction of 2,3-allenoates and organozinc reagents proceeds via a tandem Mich

Cyclobutenones 1 which are readily prepared from alkynes and keteniminium salts 2 were regiospecifically converted into Δα,β butenolides 4 or cyclopentenones 7.Reaction of 4 with diisobutylaluminium hydride yielded the corresponding substituted
