  Reactions of some pyranoside diol monotriflates with nucleophiles and bases

  摘要：

  Reaction of pyranoside diol (equatorial) monotriflates with soft, nonbasic nucleophiles is a useful way to make axial heteroatom-substituted and ''epimerized'' pyranosides, particularly where a fused acetal ring inhibits ring contraction. Among the substrates examined (1, 2,3,4,35), only 4 shows a strong tendency to give ring-contracted products. The reaction of 1-3 with more basic nucleophiles (F-, t-BuO-) leads to the anhydrosugars 8, 25, and 26, respectively. The S(N)2 reaction of 35 with tetra-n-butylammonium iodide forms the basis for a new synthesis of the Cerny epoxide 32.

• An Ezomycin Model Glycosylation
  作者：Spencer Knapp、Carlos Jaramillo、Brett Freeman

  DOI：10.1021/jo00096a022

  日期：1994.8

  A model glycosylation reaction for application to the synthesis of the ezomycin class of antibiotics is described. The ezoaminuroic thioglycoside donor 13, with a reduced and protected C-6 position and trifluoroacetamide at C-3, was prepared from the Cerny epoxide 7 by a nine-step procedure. The model D-pulo-pyranoside acceptor 20, which closely resembles an actual acceptor in the vicinity of the reacting axial hydroxyl, was synthesized from methyl beta-D-galactopyranoside 14. Glycosylation with N-iodosuccinimide/triflic acid as promoter gave the disaccharide 21 in 90% yield.
• Free radical reactions of carbohydrate derivatives in the synthesis of carbocyclic compounds. 1. Intramolecular C2?C6 cyclization of monosaccharides ? A new route to substituted cyclopentanes
  作者：A. F. Sviridov、N. K. Kochetkov

  DOI：10.1007/bf00863074

  日期：1992.3

  The feasibility of adopting a new approach to the preparation of chiral carbocyclic compounds has been demonstrated by experiment. Synthesis was achieved by way of intramolecular free radical C2-C6 cyclization of carbohydrate derivatives, which produced compounds with quaternary C2 carbon atom having a strictly defined configuration.
