Abstract
The present review covers the summary of recent progress in designing and developing Biginelli reaction strategies particularly the greener strategies with higher yields, short times and simple work-up, in which the inorganic materials such as alumina, silica gel or zeolite directly or having doped with other reagents were used as catalysts for such a type of transformations. Moreover, several aspects and available references of heterogeneous catalysis using inorganic catalysts in promoting reactions are provided briefly in this review. There is also a concise account covering the better alternative syntheses and some of improved and robust protocols of biginelli reaction for the preparation of dihydropyrimidin-2(1H)-one/thiones analogs.Keywords
