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 I2/DMSO or I2/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
分别使用 I 2 /DMSO 或 I 2 /MeCN 系统实现了从芳基甲基酮和二硫烷二基二苯胺选择性合成 2-酰基苯并噻唑和联苯[ b ][1,4]噻嗪的条件控制策略。在微波辅助、无金属条件下,所需产物仅在 15 分钟内合成,产率中等至极好(50%-90%)。该策略为苯并噻唑和双苯并噻嗪杂环化合物的有效合成中的选择性合成应用提供了巨大优势。
