Synthesis and characterization of novel 1-[(2-hydroxyethoxy)methyl]-6-(phenylthio)thymine (HEPT) and dihydro-alkylthio-benzyloxopyrimidine (S-DABO) analogs containing a benzo[d]thiazol moiety

Аннотация

A series of novel dihydro-alkylthio-benzyloxopyrimidine (S-DABO) and 1-[(2-hydroxyethoxy) methyl]-6-(phenylthio)thymine (HEPT) analogs bearing a (benzo[d]thiazol-2-yl)methyl moiety at the C⁶ position of the pyrimidine core have been synthesized. 5-Allyl-6-{(benzo[d]thiazol-2-yl)methyl}-2-thiouracil and 5-allyl-6-{(benzo-[d]thiazol-2-yl)methyl}uracil were alkylated to give, respectively, S²- and N¹- ethoxymethyl and -methylthiomethyl uracil derivatives. 5-Allyl-6-[(benzo[d]thiazol-2-yl)methyl]-2-thiouracil was also alkylated by S² with methyl bromoacetate and hydrolyzed to the corresponding acid.
