Herein, we report a metal-free and step-economic synthesis of iodo-dibenzothiazines from 2-biaryl sulfides under mild reaction conditions. The reaction involves sulfoximination of sulfides, intramolecular C–H amination, and iodization using cheap commercially available reagents. The products represent heterocyclic building blocks, readily modifiable by classical cross-coupling reactions.
在此,我们报告了在温和的反应条件下,由2-联芳基硫化物进行的无金属且经济的步骤合成碘-二苯并噻嗪。该反应包括使用廉价的市售试剂进行硫化物的硫代肟化,分子内CH氨基化和碘化。产物代表杂环结构单元,可容易地通过经典的交叉偶联反应进行修饰。
