Abstract Oxidative stress results in various pathologies and as consequence antioxidant agents have attracted uninterrupted attention. In this paper, a novel series of indole-3-carboxamidederivatives (6a–6l) were designed and synthesized based on the melatonin structure as novel antioxidants. All of them were evaluated for the antioxidant activities in vitro against human neuroblastoma SH-SY5Y cell

A novel I2-catalyzed tandem Michael addition/oxidative annulation of allenes and enamines for the construction of polysubstituted pyrroles has been developed. This protocol represents an efficient and highlyregioselective way to accessfunctionalizedpyrroles in moderate to excellent yields under mild conditions.
