gave the TSAO-5-substituted pyrimidine derivatives. Reaction of 5-halogen-TSAO derivatives with nucleophiles gave 6-substituted-TSAO analogues. Treatment of TSAO-pyrimidine analogues with POCl3/1,2,4-triazole and methylamine or di-methylamine afforded the 4-substituted pyrimidine compounds. Several substituted TSAO-thymine, TSAO-uracil, and TSAO-cytosine derivatives were found to be superior to their unsubstituted
