Abstract
An effective route to functionalized 4,5-dihydro-1H-pyrrol-3-carboxamide derivatives is described. This involves reaction of N-alkyl-3-oxobutanamides, which result from the addition of an amine to the diketene, and a primary amine in the presence of dibenzoylacetylene. The 1,3-dicarbonyl compounds obtained from the addition of an amine to diketene were trapped with a primary amine to produce (Z)-3-(alkylamino)-N1-alkyl-2-butenamide, which reacts with dibenzoylacetylene to produce 4,5-dihydro-1H-pyrrol-3-carboxamide derivatives.
