Copper(II)-catalyzed highly diastereoselective three-component reactions of aryl diazoacetates with alcohols and chalcones: an easy access to furan derivatives

Chem Commun (Camb). 2010 Apr 28;46(16):2865-7. doi: 10.1039/b924845e.

Abstract

Copper(II) complexes are efficient catalysts in three-component reactions of aryl diazoacetates with alcohols and chalcones to give gamma-hydroxyketone derivatives in high yield with excellent diastereoselectivity. The resulting coupling adducts can be easily converted into furan-containing oligoaryls, tetrahydrofuran and 2,3-dihydrofuran derivatives.
