Abstract

The reactions of [2+ 3] cycloaddition of nitrile oxides to mono-and 1, 2-disubstituted germylalkenes proceed regioselectively and resulted 5-Ge-substituted isoxazolines-2 from triethylvinyl-and triethylallylgermane and 4-Ge-isomers from β-triorganylgermylstyrene and ethyl triorganylgermylacrylates. In the latter case the reaction occurs stereospecifically: Z- germylalkenes give cis-, while E-germylalkenes yield trans-4, 5-substituted isoxazolines. ...
