Neat synthesis of c-fused pyrroles and its application to macrolactamization.

The current study describes an efficient environmental benign synthetic route of N-aryl substituted c-fused pyrrole derivatives via neat approach. It also provides base-mediated intramolecular macrolactamization using amine ester amidation reaction and leads to fused diazocine-6(5H)-one with effective yields. [ABSTRACT FROM AUTHOR]
