Synthesis and Cytokinin Activity of Two Fluoro Derivatives of N6-Isopentenyladenine
摘要:
Two derivatives of N-6-isopentenyladenine, 3 and 4, bearing either a vinylic fluorine atom or a trifluoromethyl group, were easily synthesized from known fluorinated precursors. Both derivatives 3 and 4 were found to be more active, as cytokinins, than the parent compounds zeatin (1) and N-6-isopentenyladenine (2).
