Regioselective Aminomethylation and Benzylation of N -Heterocycles via Controllable Cleavage of Triazinanes under Ambient Conditions

A site-selective reaction for the aminomethylation of imidazoheterocycles is developed using photoredox catalysis under mild conditions. A complementary metal free HFIP promoted reaction is also developed which gives corresponding anilines in good yields. Metal free conditions, s...

Rongalite-Promoted One-Pot Reductive Cyclization Strategy for the Construction of Pyrrolo[1,2-α]quinoxalines from 1-(2-Nitrophenyl)pyrroles

Abstract A transition-metal-free strategy for the synthesis of pyrrolo[1,2-α]quinoxalines and 7-methylindolo[1,2-α]quinoxaline from 1-(2-nitrophenyl)-1H-pyrrole or 3-methyl-1-(2-nitrophenyl)-1H-indole using rongalite have been developed. In this transformation, rongalite serves a...
