Abstract
Abstract Glycosidation of N-acetylneuraminic acid by phase-transfer catalysis in chloroform- aqueous alkali gave several known and some new aryl α-ketosides in a short reaction time and in good yields. The 4-methylumbelliferyl α-ketoside, the standard substrate for neuraminidase, was prepared in a yield of up to 70%. New Neu5Ac ketosides were prepared with fluorescein and the fluorescein analog, 2-methyl-6-hydroxyfluoran (2- ...
