Cu(I)-catalyzed domino reactions: efficient and selective synthesis of 4H-chromenes and naphthalenes.

Chandi C Malakar¹, Dietmar Schmidt, Jürgen Conrad, Uwe Beifuss.

Abstract

Depending on the ratio of the substrates and the reaction conditions, the Cu(I)-catalyzed domino reaction between bromobenzyl bromides and β-ketoesters exclusively yields either 4H-chromenes or naphthalenes.
