solvent-free cyclocondensation route for condensing mercaptoacetic acid with quinazolinyl-substituted azomethines has been developed using silica chloride as a catalyst for obtaining heteryl-substituted 4-thiazolidinones. The route is found to be rapid, relatively economical, and eco-friendly. The precursors, quinazolinyl azomethines have been obtained in multisteps starting from quinazolinone.
已经开发了一种有效的无溶剂的环缩合路线,该路线用于将巯基乙酸与喹唑啉基取代的偶氮甲胺进行缩合,其使用氯化硅作为催化剂来获得杂基取代的4-噻唑烷酮。发现这条路线是快速,相对经济和生态友好的。从喹唑啉酮开始,已通过多步获得了前体喹唑啉基偶氮甲碱。
