Compounds belonging to the 5-acyl-3,4-dihydropyrimidine-2-thione family were obtained using a solvent-free Biginelli condensation with or without the use of a catalyst. An unprecedented solid-phase procedure involving a polymer-supported aldehyde allowed the preparation of a series of 5-aroyl derivatives starting with crude diketones obtained from their corresponding aryl esters.
在使用或不使用催化剂的情况下,通过无溶剂 Biginelli 缩合反应获得了属于 5-酰基-3,4-二氢嘧啶-2-硫酮家族的化合物。一种前所未有的固相程序涉及聚合物支撑的醛,该程序允许从相应芳基酯的粗二酮开始,制备一系列 5-芳酰基衍生物。
