, p. 271 - 278 (2007/10/02)
A simple synthesis of title compound (3) and a number of different cycloadditions are described.C-Aroyl- and C,N-diphenylnitrones react regio- and stereoselectively to the C=C exocyclic double bond of 3, to give only spirocycloadduct (10).On the other han

Nitrile oxides add regioselectively to the carbon-carbon double bond of 3,3-methylene-5,5-dimethyl-2-pyrrolidinone (1), giving exclusively spiro-isoxazolines: 3-aryl-6-oxo-8,8-dimethyl-1-oxa-2,7-diazaspironon-2-enes 3a-l.The regiochemistry of the 1,3
