Connecting Metalation and Intramolecular Inverse Diels-Alder Strategies of 1,2,4-Triazines: A Short and Efficient Synthesis of 1-Azafluorenones

Abstract

A short high yield synthesis of polysubstituted 1-azafluorenones from 1,2,4-triazines using the metalation and intramolecular Diels-Alder reaction is described.

Key words

1,2,4-triazines - π-deficient heterocycles - 1-azafluorenones - metalations - intramolecular Diels-Alder reactions
