摘要
An efficent synthesis of 2,3-dihydropyrans from different terminal alkynes was developed. The 2,3-dihydropyrans were obtained in a few minutes through a microwave-assisted multicomponent enyne cross-metathesis/hetero-Diels-Alder reaction. Starting from C-ethynyl-ribofuranose, a new multicomponent approach to furanose-pyramose 1,3-C-C-linked disaccharides was also developed. (C) 2009 Elsevier Ltd. All rights reserved.
