摘要
The direct and catalytic displacement reactions of propargylic esters are reported. The reaction is based on the Ti(OR)(4)/alpha-hydroxy acid mediated ligand exchange. This methodology enables the inclusion of a broad range of acetylenes and aldehydes into this substitution reaction. (C) 2002 Elsevier Science Ltd. All rights reserved.
