In a similar reaction with 3-allylsulfanyl-2-arylazo-3-(1-azacycloalk-1-yl)acrylonitriles 3, dipolar cycloaddition and intramolecular cyclization competed to give a mixture of compounds 2 (major products) and 1,4,6,7,8,8a-hexahydropyrrolo[2,1-c]-1,2,4-triazines 4b-d, 1,6,7,8,9,9a-hexahydro-4H-pyrido[2,1-c]-1,2,4-triazine 4e, and 1,4,6,7,9,9a-hexahydro-1,4-oxazino[3,4-c]-1,2,4-triazine 4f (minor products) Держатели документа: Центральная научная библиотека УрО РАН Доп.точки доступа: Belskaia, N.
