Abstract
The new C-5 schiff bases derived from D-erythroascorbic acid contaning pyrimidine
unit were sy nthesized by condensation of D-erythroascorbic acid with aromatic amine
(containing pyrimidine unit)in dry benzene using glacial acetic acid as a catalyst.
D-erythroascorbic acid was sy nthesized by four steps(Schem 1), while the aromatic
amine which is containing oxopyrimidine or thiopyrimidine sy nthesized by the reaction of
chalcone urea or thiourea in acid or basic medium, respectively .
