Methyl 5-O--butyldiphenylsilyl-2-deoxy-D-threo-pentofuranoside; an approach to the syntesis of 3′-substituted-2′,3′-dideoxynucleosides including 3′-azido-3′-deoxythymidine and of 3′-substituted-2′,3′-dideoxy-C-nucleosides

short synthesis of methyl 5-O--butyldiphenylsilyl-2-deoxy-αβ-D-threo-pentofuranoside (1) from D-xylose. The syntheses of methyl 2,3-dideoxy-3-fluoro-gaβ-D--pentofuranoside and of a protected 3-azido-2,3-dideoxy-D--pentofuranose, a possible intermediate for the synthesis of 3′-azido-3'-deoxythymidine (AZT), are reported and the potential of (1) as a divergent intermediate for the preparation of 3'-substituted-2'
3,5-O-异亚丙基-αβ-D-木呋喃糖苷的Barton脱氧是短时间合成甲基5-O-丁基二苯基甲硅烷基-2-脱氧-αβ-D-苏-五呋喃糖苷的关键步骤D-木糖。2,3-二脱氧-3-氟-gaβ-D-戊呋喃糖苷甲基和受保护的3-azido-2,3 -dideoxy-D-P-呋喃呋喃糖的合成,可能是合成3'-叠氮基的中间体报道了-3′-脱氧胸苷(AZT),并讨论了(1)作为制备3′-取代的2′,3′-二脱氧核苷和C-核苷类似物的发散中间体的潜力。
