hetero atoms was synthesized. 2′-Thia-2′,3′-dideoxycytidine was the pilot compound of this series. (±)-β-2′-Thia-1′,3′-dideoxycytidine (6) and (±)-α-2′-thia-2′,3′-dideoxycytidine (7) were synthesized from (±)-3-mercapto-1,2-propanediol. The synthesis of the enantiomerically pure 2′-thia-2′,3′-dideoxycytidines (α-D-form, β-D-form, α-1-form and β-L-form) from optically pure (S)-(2,2-dimethyl-1,3-dioxalan-yl)methyl
合成了一类新的具有结合到三个杂原子上的C 1原子的核苷。2'-Thia-2',3'-二脱氧胞苷是该系列的先导化合物。由(±)-合成了(±)-β-2'-Thia-1',3'-二脱氧胞苷(6)和(±)-α-2'-thia-2',3'-二脱氧胞苷(7)。 3-巯基1,2-丙二醇。从光学纯的(S)-合成对映体纯的2'-thia-2',3'-二脱氧胞苷(α-D-形式,β-D-形式,α-1-形式和β-L-形式)还描述了对甲苯磺酸(2,2-二甲基-1,3-二氧杂丙酰基)甲基(8)及其(R)-异构体18。初步生物学结果表明(+)-β-D-2'-thia-2',3'-二脱氧胞苷(26)反对人乙型肝炎病毒中最活跃的与ED 50的3μ中号。
