Ethyl cyanoformate and methyl cyanoformate (Mander’s reagent) are both routinely used to perform C-selective ketone alkoxycarbonylations. Interestingly, both reagents were found to yield oxoalkenenitriles through an unprecedented deoxycyanation of 1,3-dicarbonyl compounds (e.g., 2-methylcyclohexane-1,3-dione). Although this method is not general, this is the first time that both Mander’s reagent and
氰基甲酸乙酯和氰基甲酸甲酯(曼德试剂)都经常用于进行 C-选择性酮烷氧基羰基化。有趣的是,发现这两种试剂都可以通过 1,3-二羰基化合物(例如 2-甲基环己烷-1,3-二酮)的前所未有的脱氧氰化产生氧代烯腈。虽然这种方法并不通用,但这是首次将 Mander 试剂和氰基甲酸乙酯用于 1,3-二羰基化合物的脱氧氰化,以制备合成有用的氧代烯烃腈。讨论了对本方法的底物范围的限制。
