7-methyl-10H-1,2,4-triazolo[3’,4’:3,4][1,2,4]triazino[5,6-b]indoles (9) have been prepared by cyclodehydrogenation of the sugar derivatives of 3-hydrazino-8-methyl-5H-1,2,4-triazino[5,6-b]indole (1). The respective linear isomer as 4 has been prepared by a dehydrative cyclization of the amides of 1. Acetylation of the sugar hydrazones and their cyclized products gave the per-N,O-acetyl derivatives. The molecular
摘要 7-甲基-10H-1,2,4-三唑并[3',4':3,4][1,2,4]三嗪基[5,6-b]吲哚的1-无环C-核苷 (9 ) 是通过 3-hydrazino-8-methyl-5H-1,2,4-triazino[5,6-b]indole (1) 的糖衍生物环化脱氢制备的。相应的线性异构体 4 已通过 1 的酰胺的脱水环化制备。糖腙及其环化产物的乙酰化得到全-N,O-乙酰基衍生物。产物的分子连通性是通过 1H、13C 和 2D H ,H Cozy 光谱建立的。
