  • Reinvestigation of the Synthesis of Per-benzylated Glycosylethenes:  A New Result
    作者:Juan Xie、François Durrat、Jean-Marc Valéry
    DOI:10.1021/jo034795e
    日期:2003.10.1
    Addition of vinylmagnesium bromide on the perbenzylated glucono-1,5-lactone gave, after reduction with Et3SiH/BF3.Et2O, a mixture of the desired beta-C-vinyl glucoside 1 and the unexpected beta-C-but-3-enyl glucoside 3 resulting from double addition of vinylmagnesium bromide on the lactone. Similar results have been obtained with the perbenzylated galactono-1,5-lactone. This side reaction was then been explored to prepare beta-C-but-3-enyl glycosides and other beta-C-glycosyl derivatives by employing different Grignard reagents. An alternative approach to the per-benzylated glycosylethenes has been studied and compared.

  • Synthesis of Constrained <i>C</i> ‐Glycosyl Amino Acid Derivatives Involving 1,3‐Dipolar Cycloaddition of Cyclic Nitrone as Key Step
    作者:Florian Rouzier、Rosanne Sillé、Ophélie Montiège、Arnaud Tessier、Muriel Pipelier、Gilles Dujardin、Arnaud Martel、Arnaud Nourry、Stéphane Guillarme

    日期:2020.11.22
    Original conformationally restricted C‐glycosyl amino acid derivatives in different series have been isolated following a two‐step strategy involving 1,3‐dipolar cycloaddition between l‐(–)‐menthone‐derived nitrone and C‐vinylglycosides as the key step. The cycloaddition reaction was highly regio‐ and stereoselective leading to corresponding cycloadducts in high yield. Simple cleavage of the chiral auxiliary
