英文摘要：

A series of 2-aryl-l,3-benzoxathiin-4-ones were synthesized by aromatic aldehyde and thio- salicylic acid under microwave irradiation for 5 min. The reaction is fast, simple and has high yield. The structures of the synthesized compounds were characterized by IR, NMR, MS spectra and elemental analy- sis.Antibacterial （Escherichia coli and Dysentery bacillus）activities of the compounds against Escherichia coli and Dysentery bacillus were evaluated. The results showed that 2-aryl-1,3-benzoxathiin-4-ones had good antibacterial activity.
