The reactions of hydrazide, mesyl hydrazide, succinyl hydrazide, and maleyl hydrazide of anthranilic acid with carbonyl compounds were studied, and new di-and tetrahydroquinazolin-4-one derivatives were prepared. The structure of one reaction product, viz., 3-methylsulfonylamino-2-(2-methylsulfonylaminophenyl)-1,2,3,4-tetrahydroquinazolin-4-one, was established by X-ray diffraction study of two crystal solvates of this compound. The characteristic features of the crystal packings of these solvates are discussed.
研究了蚁酸酰肼、甲酰基酰肼、琥珀酰肼和马来酰肼与羰基化合物的反应,并制备了新的二氢和四氢喹唑啉-4-酮衍生物。通过对一种反应产物,即 3-甲磺酰氨基-2-(2-甲磺酰氨基苯基)-1,2,3,4-四氢喹唑啉-4-酮的两种晶体溶胶进行 X 射线衍射研究,确定了该化合物的结构。本文讨论了这些溶质的晶体包合特征。
