Synthesis of Tetrahydronaphthoazetidinones, 2,5‐Dioxo‐1,4‐methanobenzoazepines and 3‐Hydroxypyrrolidinones Through Copper‐Assisted Post‐Ugi Reactions

Abstract

AbstractCopper‐assisted post‐Ugi reactions enable access to different heterocyclic systems, tetrahydronaphthoazetidinone, 2,5‐dioxo‐1,4‐methanobenzoazepine and 3‐hydroxypyrrolidinone derivatives. The described process affords complex scaffolds from readily available acyclic precursors using simple protocols.
