    • A few early examples of Fischer glycosylations of simple alkyl alcohols with sialyl hemiketals have been reported in which the acceptor must also function as the reaction solvent. See: Meindl, P.; Tuppy, H. Monatsh. Chem. 1965, 96, 816-827.

    • note
    • Use of electron-rich diarylsulfoxides such as bis(p-methoxyphenyl) sulfoxide led to incomplete activation of the C2-hemiketal, presumably a result of the attenuated electrophilicity of the sulfonium 4 (Ar = p-methoxyphenyl) relative to that of 4 (Ar = Ph).
