Article abstract of DOI:10.1016/S0040-4020(01)80370-7

Readily accessible benzisoxazolequinones 1 undergo thermal induced highly stereoselective rearrangement in solution to afford quantitatively γ-cyanomethylidenebutenolides 3.The transformation can be explained by the formation of a vinylogous nitrene inter
