On the treatment of 1,3-dialkyl-6-alkylaminouracil (1) with dimethyl acetylenedicarboxylate (DMAD), we were able to develop a new synthesis of deazapurine (pyrrolo[2,3-d]pyrimidine, 4), and proposed the plausible mechanism for the formation of 3 and 4 from the adduct [dimethyl 2-(1,3-dialkyl-6-alkylamino-2,4-dioxopyrimidin-5-yl)fumarate, 2] of 1 with DMAD.
在用乙炔二羧酸二甲酯(DMAD)处理1,3-二烷基-6-烷基氨基尿嘧啶(1)的过程中,我们能够开发出一种新的脱氮嘌呤合成方法(pyrrolo [2,3- d ] pyrimidine,4),并提出了可行的机制的形成的3和4从加合物[二甲基2-(1,3-二烷基-6-氨基-2,4- dioxopyrimidin -5-基)富马酸盐,2]的1与DMAD。
