dc.description.abstract	1,3-Dipolar cycloaddition of substituted open-chain conjugated azomethine N-oxides 1 with substituted N-arylmaleimides 2 leads to the synthesis of new stereoisomeric 2,5-diaryl-3-(o-nitro)-styryl-4H-2,3,3a,5,6,6a-hexahydropyrrolo [3,4-d] isoxazole-4,6-dione derivatives 3 in excellent yield. These stereoisomers have been characterized as cis-3A and trans-3B on the basis of their spectral measurements and are obtained in the ratio of almost 1:2 respectively in all the reaction, which is the reverse of the stereoisomers obtained through the 'Huisgen reaction’ of C,N-diaryl nitrones with N-aryl maleimides as reported earlier from these laboratories.	en_US
