Synthesis and Biological Activity of 6-(1,3-Benzoxazol-2-Yl)-5-Methylthieno-[2,3-d]Pyrimidines

An approach to the synthesis of new 6-(1,3-benzoxazol-2-yl)-5-methylthieno[2,3-d]pyrimidin-4(3H)-ones and their 4-thioanalogs was developed. Some of the synthesized compounds exhibited antimicrobial activity against strains of Bacillus subtilis bacteria and Candida albicans fungi.
