N2 - Chemical conversions of 6‐(3‐methyl‐2‐butenylamino)purine, 2iP, and 6‐(3‐methyl‐3‐butenylamino)purine, 3iP, to common products have been effected. A number of compounds related to these isomers and their ribosides have been synthesized, including 6‐(3‐hydroxy‐3‐methylbutylamino)‐9‐β‐D‐ribofuranosylpurine, 6‐(3‐chloro‐3‐methylbutylamino)purine, 6‐(3, 4‐dihydroxy‐3‐methylbutylamino) purine, and 6‐(3,4‐dihydroxy‐3‐methylbutylamino)‐9‐β‐D‐ribofuranosylpurine, and the cytokinin activities have been compared in the tobacco bioassay. The effect of 4‐hydroxyl substitution on the side chain has been noted. Diagnostic fragmentations of the side chains have been observed in the mass spectra.
