  Synthesis of 3,7-Anhydro-d-glycero-d-ido-octitol 1,5,6-Trisphosphate as an IP₃ Receptor Ligand Using a Radical Cyclization Reaction with a Vinylsilyl Tether as the Key Step. Conformational Restriction Strategy Using Steric Repulsion between Adjacent Bulky Protecting Groups on a Pyranose Ring

  摘要：

  3,7-Anhydro-D-glycero-D-ido-octitol 1,5,6-trisphosphate (5) was designed as a novel IP3-receptor ligand having a C-glycosidic structure and was synthesized via a radical cyclization reaction with a temporary connecting vinylsilyl tether as the key step. The phenyl 2-O-dimethylvinylsilyl-3,4,6-tri-O-benzyl-1-seleno-beta-D-glucopyranoside (7), in the usual C-4(1)-conformation, was successively treated with Bu3SnH/AIBN and under Tamao oxidation conditions to give a mixture of five C-glycosidic products, On the other hand, similar successive treatment of the corresponding 3,4-di-O-TBS-protected substrates 13 and 24, which were in an unusual C-1(4)-conformaion due to the steric repulsion between the bulky silyl protecting groups, gave the desired 1 alpha-C-glycosides 18 and 25, respectively, as the major products. Thus, the course of the radical cyclization was effectively controlled by a change in the conformation of the pyranose ring into a C-1(4)-form due to steric repulsion between the adjacent bulky TBS-protecting groups at the 3- and 4-hydroxyl groups. From 25, the target 5 was synthesized via phosphorylation of the hydroxyls by the phosphoramidite method. The C-glycoside trisphosphate 5 has significant binding affinity for IP3 receptor of calf cerebella.

  4,8-Anhydro-D-glycero-D-ido-nonanitol 1,6,7-trisphosphate (9), designed as a novel IP3 receptor ligand having an alpha-C-glycosidic\ structure, was synthesized via a radical cyclization reaction with a temporary connecting allylsilyl group as the key-step. Phenyl 2-O-allyldimethylsilyt-3,4-bis-O-TBS-1-seleno- beta-D-glucopyranoside (10a), conformationally restricted in the unusual C-1(4)-conformation, was treated with Bu3SnH/AIBN to form the desired alpha-cyclization product 16a almost quantitatively. On the other hand, when a conformationally unrestricted O-benzyl-protected 2-O-allyldimethylsilyl -l-selenoglucoside 15 was used as the substrate, the radical reaction was not stereoselective and gave a mixture of the alpha-and beta-products. From 16a, the target C-glucoside trisphosphate 9 was synthesized via phosphorylation of the hydroxyls by the phosphoramidite method. During the synthetic study, an efficient procedure for the oxidative C-Si bond cleavage, via a nucleophilic substitution at the silicon with p-MeOPhLi followed by Fleming oxidation, was developed. The C-glycoside 9 was found to be a full agonist for Ca2+ mobilization, although its activity was weaker than that of the natural ligand IP3. Thus, the alpha-C-glucosidic structure was shown to be a useful mimic of the myo-inositol backbone of IP3. (c) 2005 Elsevier Ltd. All rights reserved.

  An efficient method for preparing beta-C-glucosides using radical cyclization with a temporary connecting silicon tether was developed. In this reaction, conformational restriction of the substrates to the unusual C-1(4)-form is essential for the cyclization to occur. (c) 2005 Published by Elsevier Ltd.
