The stereocontrolled synthesis of new carbohydrate-derived acylsilanes with the silylcarbonyl moiety linked to the anomeric carbon via a methylene group is described. Reaction of these acylsilanes with perfluoroorganometallic reagents followed by treatment with hydrazines or amidines led to new polyfluorinated homo-C-nucleoside analogues, in a one-pot or two-step transformation, respectively.
描述了新的碳水化合物衍生的酰基硅烷的立体控制合成,其中甲硅烷基羰基部分通过亚甲基连接到异头碳。这些酰基硅烷与全氟有机金属试剂反应,然后用肼或脒处理,分别以一锅法或两步法转化产生新的多氟化高-C-核苷类似物。
