Activated nitro compounds, in the presence of dipolarophiles and a tertiary diamine (e.g., DABCO), undergo dehydration to afford directly isoxazoline derivatives, formal cycloadducts of nitrile oxides; this mild procedure is very efficient for the synthesis of the reported isoxazolines

Abstract
Activated nitro compounds, in the presence of dipolarophiles and a tertiary diamine (e.g., DABCO), undergo dehydration to afford directly isoxazoline derivatives, formal cycloadducts of nitrile oxides; this mild procedure is very efficient for the synthesis of the reported isoxazolines
