A base-mediated α-C-alkylation of ketones with secondaryalcohols has been developed. This transition metal free approach employs KOt-Bu as the base and exhibits a broad scope, allowing a range of commodity aliphatic secondaryalcohols and 1-arylethanols to be employed as alkylating agents. Aryl methyl ketones undergo selective mono-α-C-alkylation in high isolated yields (23 examples, 65% average yield)
已经开发了用仲醇进行的碱介导的酮的α- C-烷基化。这种不含过渡金属的方法采用KO t -Bu作为碱,并且具有广泛的应用范围,允许将多种商品脂族仲醇和1-芳基乙醇用作烷基化剂。芳基甲基酮经历选择性单α -C烷基化在高分离产率(23个实例中,65%平均产率)。
