  摘要：

  A series of furan C-nucleosides having a sulfur atom in the sugar ring were synthesised. The alpha and beta anomers of 3-ethoxycarbonyl-2-methyl-5-(4'-thin-D-erythrofuranosyl)furans 10 and 11 were obtained by acid treatment of (4'-S-acetyl-4'-thin-D-arabino-tetritol-1-yl)furan 9. Oxidation of 10 with m-chloroperbenzoic acid gave sulfoxide 12 as one epimer at the sulfur atom whereas 11 was transformed into sulfoxide 13 as an epimeric mixture. S-Methylation of 10 and 11 with methyl triflate led to sulfonium salts 14 and 15. The prepared compounds were found to be moderate inhibitors of alpha-L-fucosidase. (C) 2003 Elsevier Science Ltd.
