Abstract

Pyrimidin-2(1H)-ones and their derivatives show a wide range of biological, pharmaceutical and therapeutic activities [1], [2], [3], [4] and [5]. In 1893, Biginelli reported one-step synthesis of 3,4-dihydropyrimidin-2(1H)-one in alcohol using strong mineral acid [6]. The scope of the original Biginelli reaction was gradually extended by the variation of all three building blocks, allowing access to a large number of multifunctionalized pyrimidone derivatives. Although, various ...
