CP608039 (2S,3S,4R,5R)-3-amino-5 6-[5-chloro-2-(3-methylisoxazol-5-yhnethoxy)benzylamino]purin-9-yl-l-4-hydroxytetrahydrofuran-2-carboxylic acid methylamide... 

Figure 2. The effect on the fresh weight yield of tobacco callus of 6-benzylamino-purine (2) and 3-methyl-7-(3-methylbutylamino)pijrazolo[4,3-d]pyrimidine (14)...

The general preparative route to 6-(benzyloxy)purine (4), an analog of the active synthetic cytokinin-6-(benzylamino)purine, involves the reaction of 6-chloropurine with sodium benzox-ide in benzyl alcohol. ... 

The structures of two novel Pt(IV) complexes with aromatic cytokinins, 9-[6-(benzylamino)purine] and 9-[6-(furfurylamino)purine] penta-chloroplatinates have been studied by Vicha et al by the use of NMR spectroscopy including a variety of spin-spin couplings. Among others, /cpt of 18 Hz has indicated that Pt in these complexes is coordinated at the N9 atom, which is in accordance with the solid-state structure characterized by X-ray diffraction. 

Amino groups a to nitrogen are hydrolyzed to the corresponding oxo compounds (as in the purines and pteridines) in bo h acid and alkaline conditions. Schiff bases are reduced to benzylamino derivatives with borohydride.

Benzylaininopurine. ti-batzyladentne a frequently used synthetic cytokinin. In B. the furfuryl residue of natural kinetin is replaced by a benzyl group. In the plant, B. is metabolized to benzylamino-% glucofuranosylpurine, which lacks cytokinin activity. 6-(2-HydroxybenzyIainino)purine riboside has been isolated as a natural cytokinin from poplar. 

The 6-benzylamino-7-j6-D-gluco-furanosyl- and -pyranosyl-purines [(411) and (412), respectively] have been synthesized via fusion of 4-bromo-5-nitroimidazoIe...
