  Synthesis and Partial Biological Evaluation of a Small Library of Differentially-Linked β-C-Disaccharides¹

  摘要：

  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.

  The DCC mediated coupling reaction of 3,4,6-tri-O-benzyl-1,2-dideoxy-d-arabino-hex-1-enitol (5a) with a variety of sugar based carboxylic acids 6a-d gave esters 7a-d in good yield.

  Readily available S-glycoside dioxides were utilized in a Ramberg-Bäcklund rearrangement for the construction of C-linked disaccharides. This approach is ideally suited to analogue synthesis simply by variation of the alkylating agent, and is illustrated here by the synthesis of beta,beta-C-trehalose (see reaction scheme), a higher homologue of C-trehalose, and methyl C-gentiobioside.

  A convergent route to a variety of C-1-disaccharide glycals based on the olefin metathesis reaction of enol ethers and alkenes is described. The DCC-mediated coupling reaction of a variety of pentose enitols (la-c) with a number of C-5- and C-6-monosaccharide carboxylic acids (2a-e) gave the corresponding esters 3a-1 in good yield. Methylenation of these compounds was followed by ring-closing metathesis, mediated by the Schrock molybdenum catalyst 8 in warm toluene, to provide the target C-disaccharide glycals 5a-1. The formed enol ether double bond in 5a was then transformed, via standard manipulations, into a variety of C-disaccharide derivatives 21-25.
• Glycosyl iodides. History and recent advances

  日期：2009.6

  The use of glycosyl iodides as an effective method for the preparation of glycosides has had a recent resurgence in carbohydrate chemistry, despite its early roots in which these species were believed to be of limited use. Renewed interest in these species as glycosylating agents has been spurred by their demonstrated utility in the stereoselective preparation of O-glycosides, and other glycosylic compounds. This review provides a brief historical account followed by an examination of the use of glycosyl iodides in the synthesis of oligosaccharicles and other glycomimetics, including C-glycosylic compounds, glycosyl azides and N-glycosides.

• Synthesis of α- and β-<scp>d</scp>-(1→6)-<i>C</i>-Disaccharides by Wittig Olefination of Formyl <i>C</i>-Glycosides with Glycopyranose 6-Phosphoranes
  作者：Alessandro Dondoni、Helene M. Zuurmond、Alessia Boscarato

  DOI：10.1021/jo971177n

  日期：1997.11.1

  The synthesis of (1-->6)-C-disaccharides by Wittig condensation of formyl C-glycofuranosides and pyranosides with galacto-and glucopyranose B-phosphoranes is described herein. The method involves the coupling of the sugar aldehydes with the ylides and the reduction of the double bond of the resulting sugar alkenes, in most of the cases by catalytic hydrogenation. The reduction with nickel boride or diimide is employed in some special cases. O-Benzyl protective groups are removed by catalytic hydrogenation either in the course of the reduction of the double bond or in a subsequent step, while O-isopropylidene groups are cleaved by treatment with Amberlite IR-120. In this way, eight free beta-D-(1-->6)-C-disaccharides have been prepared in 26-61% overall yield starting from B-linked formyl C-glycosides. These include C-linked analogues of the biologically active disaccharides allolactose (Gal beta 1,6Glc), gentiobiose (Glc beta 1,6Glc), and N-acetylamino disaccharides (GalNHAc beta,6Gal and GalNHAc beta 1,6Glc). Moreover, the synthesis of two alpha-D-(1-->6)-C-disaccharides is described from formyl C-furanosides. The limiting condition of the synthesis of these stereoisomers is the configurational instability of the alpha-linked formyl C-glycosides under the basic conditions of the Wittig olefination.
