Abstract

2008 Furan derivatives R 0060Copper(II) Triflate-Catalyzed Nucleophilic Substitution of Propargylic Acetates with Enoxysilanes. A Straightforward Synthetic Route to Polysubstituted Furans.-An appealing alternative to currently available methods to γ-alkynyl ketones and trior tetra-substituted furans is described. The reactions are completed rapidly within a short time under mild conditions. Air or moisture are tolerated. -(ZHAN*, Z.-P.; WANG, S.-P.; CAI, X.-B.; LIU, H.-J.; YU, J.-L.; CUI, Y.-Y.; Adv. Synth.
