AbstractA direct multi-component assembling of isatin, cyclohexanone, and 2 mol of malononitrile in the presence of catalytic amount of DABCO in aq. ethanol leads to functionalized spirooxindoles at ambient temperature. The novelties of the method are multi-component route, short time duration, excellent yields of products, mild reaction conditions, easy work-up procedure, as well as isolation of product
摘要在催化量的DABCO水溶液中,直接将Isatin,环己酮和2 mol的丙二腈进行多组分组装。在环境温度下,乙醇会导致功能化的螺硫醇。该方法的新颖之处在于多组分路线,较短的持续时间,优异的产物收率,温和的反应条件,简便的后处理程序以及产物的分离和100%的碳经济性。 图形概要
