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
