Abstract

A facile iodine‐mediated unprecedented C–C cleavage by employing CuI has been established towards the synthesis of quinazolin‐4(3H)‐ones and benzo[4,5]imidazo[1,2‐c]quinazolines. This protocol involves peroxide free synthetic approach for the stable C–C bond cleavage followed by oxidative annulation to develop a library of fused N‐heterocyclic molecules.

Abstract

An unprecedented annulation of vinyl azides and 2-aminopyridines is achieved under thermal conditions to give imidazo[1,2-a]pyridines in excellent yields. A one-pot synthesis of Groebke imdidazo[1,2-α]pyridines is also presented [e.g. synthesis of compound (VI)]. [ABSTRACT FROM AUTHOR]
