The reactions of N"-acyl and N"-tosyl-substituted hydrazides of 2-aminobenzoic acid with aliphatic, aromatic, and heterocyclic aldehydes or aliphatic ketones afforded 3-acyl- and 3-tosylamido-1,2-dihydroquinazolin-4-one derivatives, respectively. The structures of the reaction products were established by NMR spectroscopy and X-ray diffraction analysis.
2-氨基苯甲酸的 N"-酰基和 N"-甲苯磺酰基取代的酰肼与脂肪族、芳香族和杂环醛或脂肪族酮反应得到 3-酰基-和 3-甲苯磺酰氨基-1,2-二氢喹唑啉-4-酮衍生品,分别。反应产物的结构通过核磁共振光谱和X射线衍射分析确定。
