A simple convenient protocol for the synthesis of methyl 2-[3-(2-(substituted phenyl)quinazolin-4-yl)thioureido] alkanoates is described. It involves the domino reaction of various amino acid esters with imidoylisothiocyanates in ethyl acetate to afford quinazoline thiourea derivatives in excellent yields. Short reaction time, mild condition, simple work up, high yields, and pure products are the major
描述了合成2- [3-(2-(取代的苯基)喹唑啉-4-基)硫脲基甲基]链烷酸酯的简单简便方案。它涉及各种氨基酸酯与亚氨基基异硫氰酸酯在乙酸乙酯中的多米诺反应,以优异的产率得到喹唑啉硫脲衍生物。反应时间短,条件温和,后处理简单,产率高和产物纯正是该方案的主要优点。从该简单方案中分离出的纯化合物的数量为24。从相应的苯甲酰苯胺制备起始的亚氨基酰基异硫氰酸酯,并通过快速色谱法纯化。
