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[7] 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.
