  The Synthesis of Some 5-Substituted-6-aza-2′-deoxyuridines

  摘要：

  5-(2-Thienyl)-1-(2-deoxy-3,5-di-O-p-toluoyl-beta-D-erythro-pentofuranosyl)-6-azauracil [VIII] and 5-cyclopropyl-1-(2-deoxy-3,5-di-O-p-toluoyl-beta-D-erythro-pentofuranosyl)-6-azauracil [X] were obtained in high yields (93.5% and 81.3% respectively) exclusively as beta anomers, by condensation of the corresponding silylated triazine bases with 2-deoxy-3,5-di-O-p-toluoyl-D-erythro-pentosyl chloride in chloroform. After deblocking both nucleosides with sodium methoxide in methanol, 5-(2-thienyl)-6-aza-2'-deoxyuridine [IX] and 5-cyclopropyl-6-aza-2'-deoxyuridine [XI] were obtained. The nucleoside IX was further acetylated, brominated with Br-2/CCl4 and deblocked with methanolic ammonia to give 6-aza-5[2-(5-bromothienyl)]-2'-deoxyuridine [XIV].
