  Synthesis and conformational studies of .beta.-(1.fwdarw.6)- and .beta.,.beta.-(1.fwdarw.1)-linked C-disaccharides

  摘要：

  An expeditious methodology for the synthesis of beta-(1-->6)- and beta,beta-(1-->1)-linked C-disaccharides has been developed. The methodology is based on the fluoride ion-mediated coupling of the (base-stable) nitronate anion derived from a glycosylnitromethane (1) and an aldehydo-hexodialdose or -hexose derivative. The carba-analogs (methylene-bridged analogs) of beta-D-Glc-(1-->6)-D-Gal and of beta,beta-trehalose (beta-D-Glc-(1-->1)-beta-D-Glc) were thus obtained in six steps only from 1 and D-galactose-derived aldehyde 4 or aldehydo-D-glucose derivative 12, respectively. The preferred conformation of the (1-->1)-linked C-disaccharides, including the symmetrical C-beta,beta-trehalose, was established on the basis of the vicinal coupling constants about the interglycosidic C-C linkages. In all the compounds of this series, the beta-C-glycosidic linkages were found to adopt preferentially the ''anti'' conformation (C2-C1-C7-C1' torsional angle = approximately 180-degrees). Our studies revealed, in particular, that the solution conformation of C-beta,beta-trehalose, in which no stereoelectronic (exo-anomeric) effects are operating, is the same as the one predicted and determined for beta,beta-trehalose, thereby demonstrating that steric effects alone are sufficient to cause the greater stability of the preferred conformation of the parent disaccharide.

  dioxides using the Meyers variant of the Ramberg−Backlund rearrangement, are described. These include a formal synthesis of a β-glycosidase inhibitor 12 and an efficient route to spirocyclic glucose derivatives 17 and 18. The synthesis of C-linked disaccharides 24, 31, and 38 and the C-glycosyl amino acid 49 using the Ramberg−Backlund rearrangement is also reported. (© Wiley-VCH Verlag GmbH, 69451 Weinheim

  A single, unified strategy for the stereocontrolled synthesis of alpha,alpha-, alpha,beta-, and beta,beta-C-trehaloses (1-3) was developed. The solution conformations of C-trehaloses 1-3, as well as their permethyl derivatives, were determined on the basis of vicinal coupling constants observed in the H-1 NMR spectra. The preferred conformations for alpha,alpha- and beta,beta-C-trehaloses (1 and 3), shown in Figure 1, were predicted and experimentally proven. A diamond-lattice analysis of alpha,beta-C-trehalose (2), shown in Figure 2, revealed the relative stability of the three staggered conformers to be 2A > 2B > 2C, and the experimental data were found to be consistent with this trend. It was demonstrated that the inversion of the C.2 or C.2' hydroxyl group of 2 affected its conformational preference in a predictable manner; The H-1 NMR spectra of alpha,beta-C-trehalose 2 provided direct experimental evidence to illustrate that the alpha-C-glycosidic bond is conformationally more rigid than the beta-C-glycosidic bond,

  The synthesis of a small library of differentially-linked beta-C-disaccharides has been carried out through the use of a radical allylation-RCM strategy. Acids 6 were prepared by Keck allylation of a suitable carbohydrate-based radical precursor, followed by oxidative cleavage of the formed alkene. Dehydrative coupling of these acids with the known olefin alcohol 5 then gave the precursor esters 7 in excellent yield. Methylenation of the esters 7 was followed by RCM and in situ hydroboration-oxidation of the formed glycals to furnish the protected beta-C-disaccharides 10 in good overall yield. Five examples were then deprotected and screened for their efficacy as enzyme inhibitors of beta-glycosidase and against several solid-tumor cell lines for in vitro differential cytotoxicity.

  Several P-C-disaccharides have been selectively synthesized by radical cyclization of two temporarily tethered functionalized monosaccharides. In this process, intramolecular addition of a carbohydrate-derived radical onto an anomeric exomethylene group, followed by axial hydrogen addition, resulted in beta stereochemistry.
