New Glycosylation Reaction Based on Alkyne-Co2(CO)6 Complex. -Fully protected glycopyranosides (I), bearing a 4-glycosyl-6-phenyl-5hexynoate residue, react with Co2(CO)8 to an alkyne-Co2(CO)6 complex. On exposure to TmsOTf it provides glucosylglucosides (III) via internal delivery of glycosyl accep
## Abstract Ring opening with molybdenum hexacarbonyl of functionalized isoxazoles is a valuable synthetic process. Tetrazolopyridine **4** and pyrazolopyridine **9** were obtained from isoxazolopyridines **3** and **6**, respectively, whereas the isoxazole **14** gave ketone **16** through the int
