Higher iodinated analogues of d-glucose: syntheses of 3-C-iodomethyl, 6-C-iodomethyl and 6-C-iodophenyl derivatives
摘要:
C-Substituted iodinated analogues of D-glucose have been prepared from diacetone-D-glucose or D-glucuronic acid derivatives; in these compounds, each hydroxyl group of glucose is present. (C) 2000 Elsevier Science Ltd. All rights reserved.

Based on the biological importance of conformationally restricted nucleoside analogues, we have efficiently synthesized 3,6-anhydro sugar moiety with 3-C-hydroxymethyl substituent from 1,2;5,6-di-O-isopropylidene-D-glucose and condensed 15 with silylated nucleobases to afford the bicyclicnucleoside with 3,6-anhydro skeleton as potential antiviral agent.
A stereoselective and efficient totalsynthesis of opticallyactive tetrodotoxin (TTX) is described. A polyfunctionalized key cyclitol compound containing branched-chains for the synthesis of TTX was prepared from d-glucose employing the Henry reaction (Nitro aldol reaction) as the key transformation. Stereoselective construction of the α-azido-aldehyde branched-chain was achieved via the key spiro
