Novel N-H and N-alkylated derivatives of meridianins have been synthesized as potential antitumor agents by a two-step conversion of N-tosyl-3-acetylindoles or N-alkyl-3-acetylindoles to the corresponding enaminones using DMF-DMA, with or without added pyrrolidine. Further cyclization with guanidine gave the corresponding 2-aminopyrimidines. The structures of the compounds, thus obtained, were proved
通过使用DMF-DMA将N-甲苯磺酰基-3-乙酰基吲哚或N-烷基-3-乙酰基吲哚经两步转化为相应的烯胺酮,合成了经络胺的新型N- H和N-烷基化衍生物作为潜在的抗肿瘤药。或不添加吡咯烷。用胍进一步环化得到相应的2-氨基嘧啶。由此获得的化合物的结构通过1 H和13 C NMR光谱,NOE实验和X射线分析证明。
