  De Novo Synthesis of the Trisaccharide Subunit of Landomycins A and E

  摘要：

  A highly enantio- and diastereoselective synthesis of alpha-L-rhodinose, beta-D-olivose as well as the trisaccharide portion of landomycin A from achiral acetyl furan has been developed. The key transformations include the palladium-catalyzed glycosylation, Myers' reductive rearrangement, diastereoselective dihydroxylation, and regioselective Mitsunobu inversion. A Mitsunobu reaction on a six member ring cis-1,2-diol was found to chemoselectively discriminate between equatorial and axial alcohols and to stereoselectively convert cis-1,2-diol into ant 1,2-diol.

  Glycosides of 2-deoxy-sugars, monosaccharides in which the hydroxyl group at C-2 is replaced with a hydrogen atom, occur widely in natural products and therefore have been the subject of intense synthetic activity. The report summarizes recent advances in this area, with a particular focus on work published since an earlier review on the topic, in 2000 (Marzabadi, C. H.: Franck, R. W. Tetrahedron 2000, 56, 8385-8417). (C) 2009 Elsevier Ltd. All rights reserved.
