The effect of solvent, acid, temperature and the reaction time on the ratio of reaction products were investigated. Trans-E-cis configuration of prepared 1,3-diisoxazolyl-1,3-dieneamines was unambiguously confirmed by 2D NMR spectra and X-ray analysis. A new mechanism of 1,3-diisoxazolyl-1,3-dieneamines formation was prop Доп.точки доступа: Beryozkina, T.; Zhidovinov, S.; Shafran, Yu.; Eltsov, O. S.; Slepukhin, P. A.
