Barbituric acid was first prepared and named in by the German chemist Adolf von Baeyerby reducing what Baeyer called Alloxanbromid alloxan dibromide' now: 5,5-dibromobarbituric acid with hydrocyanic acid and later by reducing dibromobarbituric acid with a combination of sodium amalgam and hydrogen iodide.

The cyclic hemiaminal products are analogous to tetrahedral intermediates derived from amide addition reactions and are formed in a formal polarity reversal event. Several products bear close analogy to the pharmacologically active barbiturates entry 3: amobarbital, entry butalbital.

We fully expect that the present work will provide the basis for the synthesis of novel barbituric acid derivatives and will result in the development of an array of modern synthetic methodologies to access reductive amide umpolung by electron transfer events. Keywords: electron transfer, heterocycles, reductive coupling, samarium iodide, synthetic methods.
