TL;DR: In the presence of palladium-carbon in ethanol, the authors showed stereoselective formation of the corresponding 6-deoxy-β-L-hexopyranosides.
Abstract: Hydrogenation of several 2-C, 3-C, and 4-C-methyl-branched 6-deoxyhex-5-enopyranosides in the presence of palladium–carbon in ethanol showed stereoselective formation of the corresponding 6-deoxy-β-L-hexopyranosides.

TL;DR: In this article, the present invention provides novel thiazolidine-2,4-dione derivatives possessing blood sugar-lowering action and aldose reductase-inhibitory action, their salts, their preparative processes and drugs containing them.
Abstract: The present invention provides novel thiazolidine-2,4-dione derivatives possessing blood sugar-lowering action and aldose reductase-inhibitory action, their salts, their preparative processes and drugs containing them, and relates to thiazolidine-2,4-dione derivatives represented by a general formula (1) (see formula I) [wherein R1 and R2 denote identically or differently hydrogen atoms or lower alkyl groups, R3 denotes a phenyl group, naphthyl group, benzoyl group or 5-membered or 6-membered heteroring and its benzene-condensed ring, which may have one or more substituents, A denotes a carbonyl group, sulfonyl group or bonding hand, and B denotes a lower alkylene, lower alkenylene or bonding hand], or their salts, or thiazolidine-2,4-dione derivatives represented by a general formula (2) (see formula II) [wherein R4 denotes a hydrogen atom or lower alkyl group, and R1 and R3 are same as above], or their salts.

TL;DR: In this article, the title compound was prepared by 1,3-dipolar cycloaddition of fiiran with the corresponding hydroximoyl chloride which was derived from the corresponding L-xy lose oxime.
Abstract: Source of material: The title compound was prepared (see ref. 1) by 1,3-dipolar cycloaddition of fiiran (see ref. 2 and 3) with the corresponding hydroximoyl chloride which was derived (see ref. 4) from the corresponding L-xy lose oxime (see ref. 5). The mixture of diastereomeric cycloadducts [(3aÄ,6aÄ) / (3a5,6aS) = 70 : 30] was separated by MPLC and both isomers were recrystallized from petroleum ether / ethyl acetate (see refs. 1 and 6).
