Abstract
3-Nitro-
N
-(phenylsulphonyloxy)phthalimide (
IIIa
) and
N
-(phenylsulphonyloxy)phthalimide (
IIIb
) were synthesised as key intermediates in good yield. Their structures were confirmed by
1
H NMR and FTIR spectral data. The reaction of the key intermediates with allylamine produced 3-allyl-5-nitroquinazoline-2,4-(1
H
,3
H
)-dione (
IVa
) and 3-allylquinazoline-2,4-(1
H
,3
H
)-dione (
IVb
), respectively. Luminescence emission and excitation spectra of
IVa
and
IVb
are also presented.
