  摘要：

  Displacement of the tosyloxy group in 5-O-benzyl-1,2-O-isopropylidene-4-O-(p-toluenesulfonyl)-alpha -D-glucoseptanose has yielded derivatives of 1,2-O-isopropylidene-alpha -D-galactoseptanose. Acid catalysed acetonation then gave 1,2:3,4-di-O-isopropylidene-alpha -D-galactoseptanose or 1,2;4,5-di-O-isopropylidene-alpha -D-galactoseptanose using lower acid concentrations. Reduction of the ketone derived from 1,2:3,4-O-isopropylidene-alpha -D-septanose gave 1,2;3,4-di-O-isopropylidene-beta -L-altroseptanose. Reaction of 3,4-anhydro-5-O-benzyl-1,2-O-isopropylidene-alpha -D-galactoseptanose with sodium methoxide gave 5-0-benzyl-1,2-O-isopropylidene-4-O-methyl-alpha -D-glucoseptanose and 5-0-benzyl-1,2-O-isopropylidene-3-O-methyl-alpha -D-guloseptanose. Solution-state conformations of these compounds have been deduced from their H-1 NMR spectra. (C) 2001 Published by Elsevier Science Ltd.

  Oxidation of 1,2:3,4-di-O-isopropylidene-α-D-glucoseptanose (1a) with dimethyl sulfoxide and acetic anhydride has yielded methylthiomethyl ether (1b), ketone (2), and a novel product (3). Reduction of (2) gave (1a) and its L-ido isomer (4a) which yielded the mono-O-isopropylidene compound (5a) on aqueous acid hydrolysis. Treatment of (5a) with acidified acetone gave (4a) and 1,2:4,5-di-O-isopropylidene-β-L- idoseptanose (7a). Reaction of (2) with methylmagnesium iodide yielded the two 5-C-methyl compounds (8) and (9). Hydrolysis of (8) and (9) gave 5-C-methyl-D-glucose (10) and 5-C-methyl-L-idose (11), respectively, as crystalline compounds which yielded crystalline pentaacetates on acetylation. Treatment of the p-toluenesulfonate (1c) with lithium benzoate in dimethylformamide gave the benzoate of (4a) and an elimination product (17). Reaction of (1c) with sodium methoxide in methanol yielded (17) and the isomeric elimination product (18).
