Preparation and Properties of New Surfactants Containing D-Glucosamine as the Building Block

Three types of new surfactants were prepared by using N-acetyl-D-glucosamine as a starting material.The first type of surfactant, sodium methyl 4,6-O-alkylidene-2-(carboxylatomethylamino)-2-deoxy-D-glucopyranoside, was prepared successively by the following treatments: methyl glucosidation of N-acetyl-D-glucosamine, transacetalization with an appropriate aldehyde dimethyl acetal, deacetylation, and finally reaction of the resulting methyl-4,6-O-alkylidene-2-amino-2-deoxy-D-glucopyranoside (2-amino precursor) with bromoacetic acid.The reaction of this 2-amino precursor with methyl iodide yielded the second type of surfactant, methyl 4,6-O-alkylidene-2-deoxy-2(trimethylammonio)-D-glucopyranoside iodide, in excellent yield.The last type of compound, sodium methyl 2-acetamide-4,6-O-alkylidene-3-O--2-deoxy-D-glucopyranoside, was synthesized by the reaction of methyl 2-acetamide-4,6-O-alkylidene-2-deoxy-D-glucopyranoside with 2-chloropropionic acid.Concerning the two carboxylate types of surfactants, the compounds containing a C9 or C11 hydrophobic chain in the alkylidene part showed higher water solubility than the corresponding compounds containing a C7 hydrophobic chain.Both the micelle-forming property and the ability to lower the surface tension of these carboxylate types of compounds increased with an increase in the length of the hydrophobic chain in the alkylidene part.These compounds can be applied to new acid-decomposable types of cleavable surfactants because they contain an acetal group.The acetal bond of the ammonium type of compound was cleaved more slowly than that of the corresponding carboxylate types of surfactants in 2percent aqueous HCl solution.The biodegradabilities of these compounds were also determined.KEY WORDS: Acetalization, acid decomposition properties, biodegradability, D-glucosamine, surface-active properties.

Ring-Opening Reactions of the N-4-Nosyl Hough-Richardson Aziridine with Nitrogen Nucleophiles

Dinosylated α-d-glucopyranoside was directly transformed into α-d-altropyranosides via in situ formed N-4-nosyl Hough-Richardson aziridine with nitrogen nucleophiles under mild conditions in fair to excellent yields. The scope of the aziridine ring-opening reaction was substantially broadened contrary to the conventional methods introducing solely the azide anion at high temperatures. If necessary, the N-4-nosyl Hough-Richardson aziridine can be isolated by filtration in a very good yield and high purity.

Sugar derived alkamine catalytic imine reduction method

The invention discloses a method used for catalytic reduction of imine with saccharide-derivatized amino alcohol. According to the method, imine is taken as a substrate. The method comprises following steps: 1) imine and saccharide-derivatized amino alcohol are dissolved in an organic solvent I, wherein molar ratio of imine to saccharide-derivatized amino alcohol ranges from 100:1-20; 2) trichlorosilane with 1.5 to 5 times equivalent weights is added into a solution obtained via step 1) dropwise, an obtained mixture is stirred and reacted for 12 to 36h at a temperature of -20 to 40 DEG C, and a saturated sodium bicarbonate solution is used for quenching; 3) a material obtained via step 2) is extracted with an organic solvent II, and is subjected to column chromatography isolation so as to obtain amine compounds.
