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。
