Mono and Diglycosylbutadiynes Cadiot 's dissymmetric coupling of bromoethynylsugar derivatives with therminal acetylenes led in good to excellent yields to the expected mono or diglycosylbutadiynes. In the same way, terminal acetylenic sugar derivatives could be coupled with bromoacetylenic compounds. Symmetric coupling of sugars bearing a bromoethynyl group has also been achieved. (UV., CD., IR., 1 H‐NMR.) of these compounds are reported and discussed.
