TL;DR: In this article, the epimerization of an aldose in good yield using a mild method was carried out by adding the aldoses to a solution containing a specific metal salt and specific diamine and carrying out reaction while heating.
Abstract: PURPOSE:To carry out epimerization of an aldose in good yield using a mild method, by adding the aldose to a solution containing a specific metal salt and specific diamine and carrying out reaction while heating CONSTITUTION:A salt, eg chloride, etc, of a metal selected from Co, Ca and Sr and N,N,N',N'-tetramethylethylenediamine are dissolved in methanol, etc, and an aldose is added thereto and epimerized by reacting, preferably at 30-100 degC for 5-10min The resultant reaction solution is normally adjusted near 65pH with a weak acidic solution and stirred to subsequently carry out separating action An aldohexone, eg D-glucose, etc, and aldopentose, eg D-xylose, etc, are preferred for the aldose

TL;DR: In this paper, a simple process by which 5-deoxy-L-arabinose can be efficiently produced is provided, which includes a step in which a compound represented by the formula (5) is hydrolyzed to obtain an aldose derivative represented by (6).
Abstract: [PROBLEMS] To provide a simple process by which 5-deoxy-L-arabinose can be efficiently produced. [MEANS FOR SOLVING PROBLEMS] The process includes a step in which a compound represented by the formula (5) is hydrolyzed to obtain an aldose derivative represented by the formula (6). (In the formula (5), n is an integer of 1-3 and R1 represents alkyl.) (In the formula (6), n is an integer of 1-3.)

TL;DR: In this article, a process for preparing a fructoside, especially a Fructosyl disaccharide, consisting of reacting a FRS with an alcohol or aldose in the presence of a fRS-transferase was described.
Abstract: A process for preparing a fructoside, especially a fructosyl disaccharide, comprises reacting a fructosyl saccharide such as sucrose or raffinose with an alcohol or aldose in the presence of a fructosyl-transferase, especially one derived from B subtilis BCIB 11811, 11872 or 11873 In particular, aldose is a compound of the formulain which A represents a hydrogen atom or the group CH2X, where X represents a hydrogen atom or an alkoxy group, and the fructosyl disaccharide so formed is halogenated to provide a halosucrose or halogalactosucrose sweetener
