Improved Synthesis of Substituted Quinoxalines from New N=N-Polymer-bound 1,2-Diaza-1,3-butadienes

Abstract

The first general protocol for the preparation of different N=N-polymer-bound 1,2-diaza-1,3-butadienes is reported. The utility of these supported reagents in the solid-phase in the preparation of 3-methyl quinoxaline-2-carboxylates by reaction with aromatic 1,2-diamines is presented.

1,2-diaza-1,3-butadienes - hydrazones - Michael addition - quinoxalines - solid-phase synthesis
