| Abstract: | An efficient 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-pyranose 1,3-C-C-linked disaccharides was also developed. |
