Unusual regioselectivity in [3+2] cycloaddition reactions between (E)-3-nitroacrylic acid derivatives and (Z)-C,N-diphenylimine N-oxide

Abstract

[3+2] cycloaddition reactions of -COOMe and -CN trans-substituted nitroethenes with (Z)-C,N-diphenylimine N-oxide were tested. For the contrast to most known nitroalkene/nitrone cycloaditions, the reactions studied realized with the formation of 5-nitroisoxazolidines
