-Enaminones have been synthesized by the condensation reaction of -diketones with various anilines in the presence of a catalytic amount of formic acid, mild and highly efficient acid catalyst in methanol. These condensation reactions proceed smoothly in short reaction times with near-quantitative yields. Supplemental materials are available for this article.
