Metal-Free Formal Inverse-Electron-Demand Diels–Alder Reaction of 1,2-Diazines with Ynamides

Abstract

A highly effective metal-free formal inverse-electron-demand Diels-Alder reaction of 1,2-diazines with ynamides has been developed. This catalytic protocol is more environmentally friendly and allows for the construction of 2-aminonaphthalenes and 2-aminoanthracenes from 1,2-diazines and ynamides in good to high yields with wide diversity and functional group tolerance.
