  An Olefin Metathesis Route for the Preparation of (1→6)-Linked C-Disaccharide Glycals. A Convergent and Flexible Approach to C-Saccharide Synthesis

  摘要：

  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.

  The chemical synthesis of ketopentose-5-phosphates that are involved in the pentose phosphate pathway is developed. The ketopentose phosphates, D-ribulose-5-phosphate and D-xylulose-5-phosphate, were prepared in five steps starting from known intermediates. Starting from readily available D-aldopentoses, the reduction of the corresponding furanose derivatives gave key intermediates in the form of aldopentitols

  1-O-Acetylfuranoses and pyranose 1,2-orthoesters were activated with an AuIII halide/phenylacetylene relay catalyst system, and they acted as excellent glycosyl donors. Thus, 1-O-acetyl-D-ribofuranose, 1-O-acetyl-D-lyxofuranose, and 1,2-orthoesters selectively gave the corresponding 1,2-trans glycosides, whereas 1-O-acetyl-D-arabinofuranose and 1-O-acetyl-D-xylofuranose both gave mixtures of 1,2-trans
