- 中文摘要: The reaction of ethyl-3-mercaptoquinoxaline-2-carboxylate with phenacyl bromide, ethyl chloroacetate, chloroacetonitrile or chloroacetone furnished the corresponding 3-hydroxy thieno[2,3-b]quinoxaline. 2-Cyano-3-hydroxythieno[2,3-b]quinoxaline and 2-acetyl-3-hydroxythieno[2,3-b]quinoxaline were employed as precursors in the synthesis of some novel furo[2¢,3¢:4,5]thieno[2,3-b]quinoxaline, pyrano[2¢,3¢:4,5]thieno[2,3-b]quinoxaline and other heterocyclic systems fused with thieno[2,3-b]quinoxalines. The antibacterial and antifungal activities of some the synthesised compounds were studied.
