Abstract
|
Novel pyrimidine derivatives were prepared from the reaction of 2-substituted
1,3-bis(dimethylamino)-trimethinium salts with thiourea or guanidine in the
presence of ethyl-diisopropylamine in ethanol at reflux, and also some
5-substituted pyrimidine-2-thiols has been used for the synthesis of novel disulfane
compounds. Infrared, 1H NMR, 13C NMR, and mass spectral data confirm
the molecular structures of the newly synthesized compounds. The
ultraviolet spectral behavior of these compounds was examined in DMSO and
the ?max of these compounds was studied.
