Iodine Promoted One Pot reaction of pyridin-2-amine with Arylmethyl Ketone and Selenosulfonate: Synthesis of 3-(Alkylselanyl)-2-arylimidazo[1,2-a]pyridine Under Transition-metal Free Conditions

Abstract

A new efficient approach for the I2 promoted selenium functionalization of in situ generated imidazoheterocycles from 2-bromoacetophenone and 2-aminopyridine utilizing aliphatic selenosulfonate as the selenium source under transition metal-free conditions is developed. The reaction features are good yields, easy performance, as well as applicability to versatile imidazoheterocycles via C-C bonds and C-Se bonds formation in one-pot.
