文摘

Condensation of 4,6-di(tert-butyl)-3-nitro-1,2-benzoquinone with 1,3-dimethyl-3a,9a-diphenyl-3,3a,9,9a-tetrahydroimidazo[4,5-e]- thiazolo[3,2-b][1,2,4]triazine-2,7(1H,6H)-dione in AcOH gives a new 6-(benzofuranylidene)tetrahydroimidazo[4,5-e]thiazolo[3,2-b]- [1,2,4]triazine-2,7-dione derivative, whose structure was confirmed by X-ray diffraction analysis.
