2-Isoxazoline derivatives. Part V. Regio- and stereo-selectivity in the cycloaddition of benzonitrile oxide to some cycloalkene and 2-isoxazoline derivatives
Abstract
The oxime-like CN bond of 2-isoxazolines undergoes 1,3-dipolar cycloaddition with benzonitrile oxide leading to new heterocyclic systems. The structures of the cycloadducts from benzonitrile oxide and cyclohexene systems have been established by spectral analysis and chemical evidence.
