Abstract: | Selenium dioxide oxidation of methyl α-ionylideneacetate (IIb) in ethanol afforded methyl 1′-and 4′-hydroxy-α-ionylideneacetate (IIIb and IV), methyl 3′-hydroxy-β-ionylideneacetate (V) and crude dihydroxy-ionylideneacetate (VI). The latter was oxidized with active manganese dioxide to give methyl abscisate (Ib). The growth and germination-inhibitory activity of compounds related to abscisic acid on Azuki bean seedlings and some species of seeds were examined. |
