  摘要：

  2.3.4 5 -Tetra-O-methyl-D-mannaric and galactaric acids and their bis(pentachlorophenyl) esters have been prepared as crystalline compounds, in good yields, from D-mannitol and galactitol, respectively. A new stereoregular polyamide, analogous to Nylon 66, has been prepared by polycondensation of bis(pentachlorophenyl) 2,3,4,5-tetra-O-methyl-D-mannarate with 1,6-diamino-1,6-dideoxy-2,3,4,5-tetra-O-methyl -D-mannitol dihydrochloride. The polymer has a M-w of 31,100 with a polydispersity of 1.5 (GPC). It was highly hygroscopic and soluble in ethanol, acetone, dimethyl sulfoxide, N,N-dimethylformamide and chloroform, but only slightly soluble in water. (C) 2003 Elsevier Science Ltd.

• A straightforward synthesis of perbenzylated conduritols from alditols by ring closing olefin metathesis

  日期：——

  The synthesis of perbenzylated conduritols A, E and F has been achieved in six steps by formal conversion of galactitol, D-mannitol and D-glucitol into the respective terminal dienes, followed by ring closing olefin metathesis.

  通过将半乳糖醇、D-甘露醇和D-葡萄糖醇正式转化为相应的末端二烯，随后进行环闭合烯烃复分解反应，实现了苯甲酰化康杜利托醇A、E和F的六步合成。

• Synthesis of <i>allo</i>- and <i>epi</i>-Inositol via the NHC-Catalyzed Carbocyclization of Carbohydrate-Derived Dialdehydes

  A synthesis of carbocyclic sugars from carbohydrate-derived dialdehydes using organocatalysis has been developed. Sorbitol, mannitol, and galactitol were converted via 1,6-tritylation, perbenzylation or permethylation, detritylation, and Swern oxidation into 2,3,4,5-tetra-O-alkyl-dialdoses that were cyclized via the benzoin reaction promoted by a triazolium carbene. Manno- and galacto-configured dialdehydes gave predominantly single inosose stereoisomers in up to 75% yield if the mixture was acetylated prior to isolation while the gluco-dialdehyde afforded a mixture of three stereoisomers in 61% overall yield. The inososes were stereospecifically reduced using sodium borohydride and then deprotected to give allo- and epi-inositol in good yield that confirmed the structural and stereochemical assignments.
• A Novel Carbohydrate-Derived Side-Chain Polyether with Excellent Protein Resistance
  作者：Mark Metzke、Jane Z. Bai、Zhibin Guan

  DOI：10.1021/ja0349507

  日期：2003.7.1

  A novel carbohydrate-derived side-chain polyether was synthesized as a new biomaterial by condensation polymerization of monomers derived from natural occurring carbohydrates. Surface plasmon resonance spectroscopy studies demonstrated that this side-chain polyether has excellent resistance to nonspecific protein adsorption. The protein resistant capability of the side-chain polyether is comparable to that of oligoethylene glycol, a main-chain polyether that is, to date, the best protein resistant material. In addition to the excellent biocompatibility, the new polymer also combines biodegradability and functionalizability. With these combined good properties, this side-chain polyether is envisioned as a new biomaterial for many potential biomedical applications.
