Abstract
The product obtained in a reaction of 3-methyl-4-nitro-5-styrylisoxazo le (1) has been shown to be a diastereomeric mixture of two cyclobutyl dimers by NMR. A combination of H-1, C-13 spectra including DEPT, ASI S, 2D COSY and nOe techniques has established that centrosymmetric cyc lobutane (7) and the isomer (8) with plane of symmetry are in 2:1 prop ortion.
