Cycloaddition of α‐( tert ‐Butylthio)acrylonitrile to C,N ‐Diphenylnitrone The radicophilic olefin 1a undergoes a smooth 1,3‐dipolar cycloaddition to C,N ‐diphenylnitrone ( 4 ) with formation of 5,5‐disubstituted isoxazolidines 5A, B as the major products accompanied by minor amounts of the regioisomeric adducts 6 and 7 . No products other than 1: 1 cycloadducts have been detected.
