Abstract
Reaction of ethyl 3-amino-5-phenylfuran-2-carboxylate
1
with benzoyl isothiocyanate gave 2,3-dihydro-6-phenyl-2-thioxofuro[3,2-
d
]pyrimidin-4-one. Compound
3
was reacted with benzyl chloride to afford 2-(benzylthio)-6-phenylfuro[3,2-
d
]pyrimidin-4-one
4
and also reacted with bromoglucopyranosyl to give
S
-glycoside
5
. The cyclization of ethyl 3-amino-5-phenylfuran-2-carboxylate
1
using thiourea, aniline, and carbon disulfide gave phenylfuro[3,2-
d
]pyrimidine derivatives. The pharmacological properties for the synthesized compounds were reported.
