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.
