for the synthesis of ethyl 2-amino/aryloxy-3-aryl-4-oxo-5-phenyl-4,5dihydro-3H-pyrrolo[3,2-d]pyrimidine-7-carboxylate derivatives has been developed. The main process involved the reaction of diethyl 1-phenyl-3-((triphenylphosphoranylidene)amino)-1H-pyrrole-2,4-dicarboxylate and aromatic isocyanates, followed by addition of amines/phenols in the presence of catalytic amount of sodium ethoxide or solid
一种高效选择性合成 2-氨基/芳氧基-3-芳基-4-氧代-5-苯基-4,5二氢-3H-吡咯并[3,2-d]嘧啶-7-羧酸酯衍生物的方法发达。主要过程涉及 1-苯基-3-((三苯基正膦亚基)氨基)-1H-吡咯-2,4-二羧酸二乙酯和芳香族异氰酸酯的反应,然后在催化量的乙醇钠存在下加入胺/酚类或固体碳酸钾。
