SYNTHESIS AND PROPERTIES OF AZOLES AND THEIR DERIVATIVES. 54. THE REGIOSELECTIVITY OF [2+3] CYCLOADDITION OF C,C,N-TRIPHENYL- AND <i>Z</i>-C,N-DIPHENYLNITRONES WITH β- AND α- SUBSTITUTED NITROETHYLENES IN LIGHT OF FRONTIER MOLECULAR ORBITAL THEORY

Using quantum-chemical calculations we have carried out an analysis of frontier molecular orbital interactions in the [2+3] cycloaddition reactions of C,C,N-triphenyl- and Z-C,N-diphenylnitrones with β- and α-substituted nitroethylenes. In all of the examples studied the orbital effects lead to the formation of the corresponding 4-nitroisoxazolidines.
