Photoinitiated glycosylation at 350 nm
Cumpstey, Ian,Crich, David
experimental part, p. 469 - 485 (2012/06/15)
A method for photochemical activation of glycosyl donors is presented. Selenoglycosides were activated by single-electron transfer using a photooxidant, N-methylquinolinium hexafluorophosphate, as photosensitizer and a toluene cosolvent as cosensitizer under irradiation at 350 nm. In this way we were able to synthesize glycosides including (1→6)-linked disaccharides. Benzyl ethers and benzoate esters were compatible with these conditions, allowing potentially synthetically useful transformations. The major by-products were due to hydrolysis; the reactions required the presence of oxygen and were run in air.

Exposure of thiostannane to acetyl or methyl glycosides in the presence of a catalytic amount of Bu2Sn(OTf)2 provides thioglycosides in good yields. Selenoglycosidation is achieved in a like manner by use of selenostannane.
Electron Spin Resonance Spectroscopic Investigation of Carbohydrate Radicals. Part 2. Conformation and Configuration in Pyranos-1-yl Radicals

Carbohydrate free radicals were regiospecifically generated at C-1 of acylated and alkylated pyranosyl derivatives in non-aqueous solution and their conformations were deduced from the hyperfine splittings of their e.s.r. spectra.The preferred conformatio
