agents and a1aantagonists. Since the first straightforward synthetic method for DHPMs was reported by Biginelli in 1893, many improved protocols were developed. Not only new catalysts and reaction conditions were explored but also some novel reactive species were formed. The scope of the Biginellireaction extended to various building blocks, so a large number of multifunctional pyrimidine derivatives with
