DMF Dimethyl Acetal as Carbon Source for α-Methylation of Ketones: A Hydrogenation-Hydrogenolysis Strategy of Enaminones

A novel heterogeneous catalytic hydrogenation hydrogenolysis strategy has been developed for the alpha-methylation of ketones via enaminones using DMF dimethyl acetal as carbon source. This strategy provides a very convenient route to alpha-methylated ketones using a variety of ketones without any base or oxidant.
