The synthesis of α/β-L-fucosylated cysteamine, 3-thiopropionic acid, and 3-thioacetic acid derivatives as building blocks for the preparation of S-neofucopeptides is shown. These compounds were used in the synthesis of new thiofucosides derivatives (8α, 9α, 9β, 10α, 22α, 22β, 24α, 26α) that show affinity towards E- and P-selectins. They constitute a new series of hydrolytically stable and low-molecular-weight

The García-González reaction of D-glucose and ethyl acetoacetate generated ethyl 5-[(1′S)-D-erythrosyl]-2-methyl-3-furoate (5), which was converted to ethyl 5-[(1′R)-1′,4′-dideoxy-1′,4′-imino-D-erythrosyl]-2-methyl-3-furoate (3c) and to ethyl 5-[(1′S)-1′,4′-dideoxy-1′,4′-imino-D-erythrosyl]-2-methyl-3-furoate (4c). Similar methods were developed to generate other carboxylic acid derivatives such as

The preparation of [(2S,3S,4R)-3,4-dihydroxypyrrolidin-2-yl]furan derivatives in a stereoselective route starting from D-glucose and ethyl acetoacetate is presented. Ethyl ester (6), N,N-diethylamide (7) and N-isopropylamide (8) have been tested towards 25 glycosidases. Ester (6) is a selective inhibitor of beta-galactosidases. The new compounds represent a new type of imino-C-nucleoside analogues. (C) 2002 Published by Elsevier Science Ltd.
