Abstract:

Allylic thioethers are versatile tools in organic synthesis, acting as precursors in enantioselective synthesis as well as privileged substrates in crossmetathesis. Moreover these compounds are known to possess anticancer properties. Recently, the chemical literatures revels a great interest in the synthesis of allylic thioetheres. However, these methodologies require either Lewis or Brønsted acid to catalyze the synthesis of allylic thioetheres generating unwanted byproduct, beyond expensive cost of these catalyst. In line with our interest in organochalcogenide herein we report the synthesis of allylic thioetheres under microwave irradiation and solvent- and catalyst-free conditions (Scheme 1).
