    (1'S)-1-Methyl-cis-zeatin [(1'S)-2] and its 9-β-D-ribofuranoside [(1"S)-4] were synthesized from L-alanine through [S-(Z)]-4-amino-2-methyl-2-penten-1-ol ethanedioate [(S)-3]. Condensations of 2-hydroxy-6-methylthiopurine (16) with the trans-isomeric amine salt [(S)-15], its enantiomer [(R)-15], and the racemic modification [(±)-15] furnished (1'S)-, (1'R)-, and (±)-2-hydroxy-1'-methyl-trans-zeatine (6), respectively. A similar condensation of 16 with methylamine yielded 2-hydroxy-N6-methyladenine (7). These adenine derivatives were tested for cytokinin activity in the tobacco callus bioassay, and the order of their activity was (1'R)-6>(±)-6>(1'S)-2>7; on the other hand, (1"S)-4 and (1'S)-6 were completely inactive at 0.1-100μM and 0.01-10μM concentrations, respectively. As a result of the above syntheses of (1'R)-6, (1'S)-6, (±)-6, and 7, the gross structures of a marine green alga cytokinin and of a blue coral cytokinin were established to be 6 and 7, respectively.
    以L-丙氨酸为原料,通过[S-(Z)]合成(1'S)-1-甲基-顺式玉米素[(1'S)-2]及其9-β-D-呋喃核苷[(1"S)-4] -4-氨基-2-甲基-2-戊烯-1-醇乙二酸酯[(S)-3] 2-羟基-6-甲基硫嘌呤(16)与反式异构胺盐[(S)-15]、其对映体[(R)-15]和外消旋体[(±)-15]提供(1'S)-、(1'R)-和(± )-2-羟基-1'-甲基-反式-玉米丁(6),分别用甲胺进行类似的缩合,得到2-羟基-N6-甲基腺嘌呤(7)。烟草愈伤组织生物测定中的细胞分裂素活性,其活性顺序为(1'R)-6>(±)-6>(1'S)-2>7;另一方面,(1"S)-4和(1'S)-6 分别在 0.1-100μM 和 0.01-10μM 浓度下完全失活。作为(1'R)-6、(1'S)-6、(±)-6和7的上述合成的结果,海洋绿藻细胞分裂素和蓝珊瑚细胞分裂素的总体结构被确定为分别为6和7。

  • Purines. XXXV. Synthesis and cytokinin activity of racemic 1'-methylzeatin.

    Racemic 1'-methylzeatin [(±)-2] has been synthesized from (±)-alanine [(±)-3] through a 9-step route proceeding via the intermediates (±)-4-(±)-11. In the tobacco callus bioassay, (±)-2 exhibited a strong cytokinin activity at 0.04- 1μM concentration, a range between the optimum concentrations of both enantiomers (1'R)-2 and (1'S)-2.
    外消旋1'-甲基玉米素[(±)-2]是由(±)-丙氨酸[(±)-3]通过中间体(±)-4-(±)-11以9步法合成的。在烟草胼胝体生物测定中,(±)-2 在 0.04-1μM 浓度下表现出很强的细胞分裂素活性,这一浓度范围介于对映体 (1'R)-2 和 (1'S)-2 的最佳浓度之间。
