Abstract
The four-component condensation of ethyl acetoacetate, phenylglyoxal hydrate, barbituric acid, and primary amines was used to obtain polysubstituted pyrroles containing a barbituric acid fragment. In some cases, by-products formed by the three-component condensation of phenylglyoxal hydrate, barbituric acid, and amines were isolated.
