The current strategy is the first example of amino acid promoted, green synthesis of a series of thiazolo[3,2-a]pyrimidines via the formation of CN and CC bonds. The major advantages of the present methodology such as recyclability of catalyst, operational simplicity, easy scale-up, wide substrate scope, easy work-up, inexpensive, excellent yields, and high atom economy make it a distinct improvement
描述了一种高效、一锅、多组分、
L-精氨酸催化的
噻唑并[3,2-a]
嘧啶合成方法。
L-精氨酸是一种容易获得、可
生物降解、廉价且有前途的
生物有机分子。目前的策略是通过形成C - N和C - C键来绿色合成一系列
噻唑并[3,2-a]
嘧啶的第一个例子。本方法的主要优点,例如催化剂的可回收性、操作简单、易于放大、底物范围宽、易于后处理、廉价、优异的产率和高原子经济性,使其比现行策略有明显的改进。
