this study, we developed a general iron-catalyzed α-methylenation of ketones by using N,N-dimethylacetamide as the one-carbon source. Various ketones, including aryl and alkyl ketones, enones, and dicarbonyl compounds were well tolerated to yield the corresponding α,β-unsaturated carbonyl compounds in the presence of an iron catalyst, peroxides, and N,N-dimethylacetamide under aerobic conditions.
在这项研究中,我们通过使用 N,N-二甲基乙酰胺作为单碳源开发了一种通用的铁催化酮的 α-甲基化。在有氧条件下,在铁催化剂、过氧化物和 N,N-二甲基乙酰胺的存在下,各种酮,包括芳基和烷基酮、烯酮和二羰基化合物,都具有良好的耐受性,可以产生相应的 α,β-不饱和羰基化合物。
