Under borrowing hydrogen conditions, NHC–iridium(I) catalyzed the direct or one-pot sequential synthesis of α,α-disubstituted ketones via the alkylation of secondary alcohols with primary alcohols is reported. Notably, the present approach provides a new method for the facile synthesis of α,α-disubstituted ketones and featured with several characteristics, including a broad substrate scope, using easy-to-handle
据报道,在借用氢的条件下,NHC-铱(I)催化通过仲醇与伯醇的烷基化直接或一锅法连续合成α,α-二取代的酮。值得注意的是,本方法提供了一种易于合成α,α-二取代酮的新方法,该方法具有多种特征,包括广泛的底物范围,使用易于处理的醇作为起始原料,并在有氧条件下进行反应。此外,通过向反应混合物中添加外部氢源,选择性地一锅形成β,β-二取代的醇。
