ChemInform Abstract
Methyl S-dihydroorotate (Ia) is consecutively converted to the racemic hydantoin-5-acetates (II). Their structures are confirmed by X-ray analysis of (IIe). The reduction product obtained from (III) is shown to be (Ib) and not the isomeric hydantoin (IIc). (IR-, MS-, 1H-NMR-data).
