  The correctness of the gross structure of the marine green alga cytokinin 2-hydroxy-1'-methylzeatin (1) has been confirmed as a result of the chiral syntheses of (1'R)-1 and (1'S)-1. An indirect comparison of the cytokinin activity of the natural cytokinin with those of the synthetic enantiomers suggests that the R configuration may be assigned to the natural one unless it would be racemic.

  (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.
