Thermal Rearrangement of Benzisoxazole- and Naphthisoxazolequinones in Solution and in the Solid State. Stereoselective Synthesis of γ-Cyanomethylidenebutenolides.

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

A facile synthesis of alkylidenebutenolides via thermal rearrangement of benzisoxazolequinones

Benzisoxazolequinones 1 readily accesible from 2-carboxy-1,4-hydroquinone undergo thermic induced highly stereoselective rearrangement in solution to produce quantitatively γ-cyanomethylidenebutenolides 2.
