Aldehyde, alcohol, azide, and alkyne undergo smooth coupling by means of acetal formation, azidation, and a Subsequent 'click reaction' in the presence of copper(II) triflate and copper metal in acetonitrile to furnish alpha-alkoxy-1,2,3-triazoles in good yields. The method provides a convenient route to prepare a wide range of triazoles in a one-pot operation via a four-component reaction. (C) 2009 Elsevier Ltd. All rights reserved.
