A number of plant tissues convert approximately 20-25% of the cytokinin, 6-benzylaminopurine, into a stable, long-lived derivative previously identified tentatively as 7-glucofuranosyl-6-benzylaminopurine. This substance has been synthesized by an unambiguous route and shown not to be identical with the long-lived metabolite. Synthesis and comparison of 7-β-glucopyranosyl-6-benzylaminopurine with the metabolite proves that to be the structure of the metabolite instead.
