摘要：

A detailed investigation on fluorination of 1,3,5-tri-O-benzoyl-alpha -D-ribofuranose-2-sulphonate esters is reported. Various combinations of sulfonate esters, fluorinating agents and solvents were evaluated in this study. Organic ammonium fluoride, in particular n-Bu4NF, was found to be better fluorinating agent than inorganic fluoride, and 1,3,5-tri-O-benzoyl-alpha -D-ribofuranose-2-trifluoramethylsulphonate ester appeared to be the best substrate. The developed method is suitable for stereospecific (arabino) incorporation of radiofluorine (F-18) into the sugar moiety. (C) 2000 Elsevier Science S.A. All rights reserved.
