• Metal-free C–H mercaptalization of benzothiazoles and benzoxazoles using 1,3-propanedithiol as thiol source
  作者：Yan Xiao、Bing Jing、Xiaoxia Liu、Hongyu Xue、Yajun Liu

  DOI：10.3762/bjoc.15.24

  日期：——

  A facile and effective C–H functionalization strategy for the synthesis of 2-mercaptobenzothiazoles and 2-mercaptobenzoxazoles is described. 1,3-Propanedithiol was employed to convert benzothiazoles and benzoxazoles to the corresponding heteroarylthiols in the presence of potassium hydroxide and DMSO. This novel protocol is featured by direct C–H mercaptalization of heteroarenes and a simple reaction system.

  2‐(benzo[d]thiazol‐2‐ylthio)‐1‐(3,4‐dihydroxyphenyl)ethanones was found to inhibit Pma1p, with the most potent IC50 value of 8 μm in an in vitro plasma membrane H+‐ATPase assay. These compounds were also found to strongly inhibit the action of proton pumping when Pma1p was reconstituted into liposomes. 1‐(3,4‐Dihydroxyphenyl)‐2‐((6‐(trifluoromethyl)benzo[d]thiazol‐2‐yl)thio)ethan‐1‐one (compound 38) showed
