  Sonogashira reactions of α- and β-1-ethynyl-2-deoxyribosides: synthesis of acetylene-extended C-nucleosides

  摘要：

  An improved practical protocol for the synthesis of both anomers of 1-ethynyl-2-deoxiribosides 1 was developed. The Sonogashira coupling of ethynyldeoxyribosides 1 with various aryl- and heteroaryl halides was carried out under various conditions. It was found that the use of copper-free coupling protocols could reduce the oxidative dimerisation in favour of arylalkynyldeoxyriboside formation. (C) 2009 Elsevier Ltd. All rights reserved.

  A simple two-step method for the selective preparation of anomerically pure 1α- and 1β-(indol-2-yl)deoxyribose derivatives was developed. The synthesis was based on the Sonogashira reaction of 1α- and 1β-ethynyldeoxyribose and 2-haloanilines followed by a Pd-complex catalyzed cyclization to the corresponding indolyldeoxyribosides.

  developed. Cyclotrimerization of C-alkynyldeoxyriboside with a variety of substituted 1,6-heptadiynes to the corresponding C-aryldeoxyribosides was catalyzed by various transition metal complexes (Rh, Ir, Co, Ru, and Ni). The most general catalyst proved to be RhCl(PPh(3))(3), which could catalyze most of the cyclotrimerizations in high yields (52-95%).

• Co- and homocyclotrimerization reactions of protected 1-alkynyl-2-deoxyribofuranose. Synthesis of C-nucleosides, C-di- and C-trisaccharide analogues

  Cyclotrimerization of beta- or alpha-ethynyl-3,5-di-O-toluoyl-2-deoxy-D-ribofuranose with alpha,omega-diynes proceeded smoothly under Rh-catalysis to afford the corresponding beta- or a-benzene C-nucleoside derivatives. Analogous co-cyclotrimerization of alpha- or beta-propynyl- and -phenylethynyl-3,5-di-O-toluoyl-2-deoxy-D-ribofuranose with alpha,omega-diynes gave the corresponding arene derivatives only under microwave irradiation in the presence of a Rh-catalyst in moderate yields. Attempted homocyclotrimerization of beta- or alpha-ethynyl-3,5-di-O-toluoyl-2-deoxy-D-ribofuranose under Rh-catalysis led only to enynes while the use of Ru-catalyst gave the desired 1,2,4- and 1,3,5-tri-(2-deoxyribofuranose-1-yl)benzene.
