Pyrimidine synthesis starting from acrylonitrile has been known since the 1960s. The new Lewis acid-catalyzed condensation reaction allows the synthesis of 4-aminopyrimidines starting from the easily accessible chemical acrylonitrile without the need for carcinogenic chemicals and costly derivatization in up to 90% yield. The method is versatile and applicable for industrial-scale synthesis of biologically
自1960年代以来,就已知从丙烯腈开始合成嘧啶。新的路易斯酸催化的缩合反应可从易于获得的化学丙烯腈开始合成4-氨基嘧啶,而无需致癌化学物质,且衍生化成本高达90%。该方法用途广泛,可用于工业规模的生物相关物质的合成,例如维生素B1和甲氧苄啶。
