the conversion was found to be not sensitive to the presence of air or atmospheric moisture. The methodology was found to be general and a wide variety of spiro 2,3-dihydroquinazolin-4(1H)-ones were prepared from 2-aminobenzamides and cyclic ketones within a few minutes in quantitative yields. The products isolated do not require any chromatographic purification. This method provides advantages such
Amberlyst-15已被确认为在室温下超声辐射下合成螺旋2,3-二氢喹唑啉-4(1 H)-ones的绿色且可重复使用的催化剂。该反应可以在敞口烧瓶中进行,因为发现该转化对空气或大气水分的存在不敏感。发现该方法是通用的,并且有多种螺2,3-二氢喹唑啉-4(1 H由2-氨基苯甲酰胺和环状酮在几分钟内以定量收率制备1)-酮。分离出的产物不需要任何色谱纯化。该方法具有诸如缩短反应时间,高产物收率和简单操作程序的优点。当在体外测试时,某些化合物显示出分支酸突变酶抑制特性。
