Abstract

A highly efficient and green four-component difunctionalization of styrenes with KSCN and imidazo[1,2-a]pyri- dines was developed. In this protocol, readily available KSCN was used as a sulfur source and inexpensive K₂S₂O₈ was used as a free radical initiator. A series of C-3 thiolated imidazopyridine analogues were synthesized, in which hydroxyl group and aryl or alkyl group were incorporated. A novel method for the synthesis of multifunctionalized imidazopyridines was established.

Key words: difunctionalization, thiolation, imidazopyridines, styrenes, potassium thiocyanate
