The synthesis of a new series of 1,2-disubstituted carbonucleoside analogues, pyrimidines of general structure I, is reported. These compounds were prepared in good yield from (′)-6-azabicyclo[3.2.0]hept-3-en-7-one (1) via two synthetic routes that involve NaBH 4 -mediated C-N bond cleavage as the key step. The uracil derivative Ia was halogenated with Cl, Br, and I at position 5 by treatment with
报道了一系列新的 1,2-二取代碳核苷类似物,即通式 I 嘧啶的合成。这些化合物是由 (')-6-azabicyclo[3.2.0]hept-3-en-7-one (1) 通过两种合成路线以高产率制备的,其中 NaBH 4 介导的 CN 键断裂是关键步骤。通过用相应的 N-卤代琥珀酰亚胺处理,尿嘧啶衍生物 Ia 在 5 位被 Cl、Br 和 I 卤化。
