摘要
A condition-controlled strategy for selectively synthesis of 2-acylbenzothiazoles and bibenzo[b][1,4]thiazines from aryl methyl ketones and disulfanediyldianilines was realized using I_(2)/DMSO or I_(2)/MeCN systems,respectively.The desired products were synthesized in only 15 min with moderate to excellent yields(50%-90%)under microwave-assisted,metal-free conditions.The strategy provides a great advantage for selective synthetic applications in the efficient synthesis of benzothiazoles and bibenzothiazines heterocycle compounds.
