Ethyl 2-amino-4-aryl-1,4-dihydro-6-phenylpyrimidine-5-carboxylates readily react, under microwave irradiation and solvent-freeconditions, with 3-formylchromone or diethyl (ethoxymethylene)malonate to yield novel pyrimido[1,2-a]pyrimidines. The structure of the final products, deduced from the spectral data and confirmed by X-ray analysis, allows us to suggest reaction pathways.
2-氨基-4-芳基-1,4-二氢-6-苯基嘧啶-5-羧酸乙酯在微波辐射和无溶剂条件下,很容易与3-甲酰基色酮或丙二酸二乙酯(乙氧基亚甲基)反应生成新的嘧啶基[1]。 ,2- a ]嘧啶。从光谱数据推导并通过X射线分析确认的最终产品结构,使我们能够提出反应途径。
