Abstract
The azetines (I), obtained from the corresponding (thio)lactams in a known manner, react with nitrile oxides generated in situ to give the 1,3-dipolar cycloadducts (III).
ChemInform Abstract
The azetines (I), obtained from the corresponding (thio)lactams in a known manner, react with nitrile oxides generated in situ to give the 1,3-dipolar cycloadducts (III). Further examples are given in the original paper. The analogous reaction between azetines and nitrile sulfides, azomethine ylides, nitrones, or aryl azides is not observed.
