Abstract
The domino cycloaddition-thermal rearrangement of nitrile oxides and m ethylenespiro[2.2]pentane gives 5-azaspiro[2,5]oct-6-en-8-one derivati ves; with a nitrone the process complements the one using bi(cycloprop ylidene) for the synthesis of alpha-spiro cyclopropanated heterocyclic ketones.
