Metal-free C-H mercaptalization of benzothiazoles and benzoxazoles using 1,3-propanedithiol as thiol source.


ABSTRACT: 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.
