  N-Glycosylation of 2,3-dideoxyfuranose derivatives having a (diethoxyphosphorothioyl)difluoromethyl group at the 3α-position

  摘要：

  Lewis acid-mediated N-glycosylation of 2,3-dideoxyribofunanosides having a (diethoxyphosphorothioyl)difluoromethyl group at the 3alpha-position with silylated nucleobases was examined. The phosphorothioyldifluoromethyl was found to be an effective functional group for the diastereoselective synthesis of beta-N-1-pyrimidine-nucleotide analogues 26 and 28-30. However, the method was not useful for the diastereoselective synthesis of adenine nucleotide analogues. The nucleotide analogue 26 was transformed to the difluoromethylene-phosphonate analogue 31 of thymidine-3'-phosphate by oxidation with m-CPBA, followed by aqueous. work-up. (C) 2003 Elsevier Ltd.

  N-Glycosylation of 2,3-Dideoxyfuranose Derivatives Having Difluoro-methylene-phosphonate and -phosphonothioate Functionality at the 3α-Position

  摘要：

  TiCl4介导的N-糖苷化反应对2,3-脱氧核糖糖苷进行研究，这些糖苷在3α位具有二氟亚甲基磷酸酯或磷酸硫酯功能团，与硅基化的嘧啶类化合物反应。磷酸酯功能团是一个良好的指向基团，能够以高的差异选择性诱导α-N-糖苷化，得到α-N-3-嘧啶核苷酸类似物13。磷酸硫酯是一个有效的功能团，可以以良好的差异选择性生成β-N-1-嘧啶核苷酸类似物18a-c。核苷酸类似物18a经过MCPBA氧化处理后，经水相后处理转化为胸腺苷-3¢-磷酸的二氟亚甲基磷酸酯类似物20。

  TiCl4-Mediated N-glycosylation of 2,3-dideoxyribofunanosides having a difluoromethylene-phosphonate or -phosphonothioate functional group at the 3α-position with silylated pyrimidines was examined. The phosphonate functional was a good directing group to induce α-N-glycosylation for α-N 3-pyrimidine-nucleotide analogue 13 in high diastereoselectivity. The phosphonothioate was an effective functional group to give β-N 1-pyrimidine-nucleotide analogues 18a-c with good diastereoselectivity. The nucleotide analogue 18a was transformed to the difluoromethylenephosphonate analogue 20 of thymidine-3¢-phosphate by oxidation with MCPBA, followed by aqueous work-up.
