Intramolecular inverse electron demand Diels–Alder reactions of tryptamine with tethered heteroaromatic azadienes

Abstract

The inverse electron demand Diels–Alder cycloadditions of heteroaromatic azadienes have proven to be valuable, fundamental reactions for the construction of various heterocyclic compounds. 2 Indole and its derivatives have been established as suitable dienophiles in this …
