Application of α-amino acids for the transition-metal-free synthesis of pyrrolo[1,2-a]quinoxalines

Org Biomol Chem. 2017 Aug 30;15(34):7157-7164. doi: 10.1039/c7ob01688c.

Abstract

A practical and concise protocol for the efficient synthesis of pyrrolo[1,2-a]quinoxalines from readily available α-amino acids and 2-(1H-pyrrol-1-yl)anilines under transition metal-free conditions has been established. This protocol, which includes the formation of new C-C and C-N bonds, features a wide substrate scope with a broad range of functional group tolerance.
