The reaction of β-amino ketones with bis(acetonitrile)dichloropalladium(II) in the presence of triethylamine gives the corresponding enaminones regioselectively. The cyclic β-amino ketones can be converted into the corresponding exocyclic enaminones. The enaminones thus obtained are versatile synthetic intermediates. The reaction of (E)-enaminones with organocuprates gave the corresponding (E)-α,β-unsaturated ketones.
Eleven new imine derivatives 6 containing 1H-1,2,4-triazole and thiazole rings were synthesized by the condensation of 5-((1H-1,2,4-triazol-1-yl)methyl)-4-tert-butylthiazol-2-amine with various substituted benzaldehydes. The structures of the title compounds were characterized by H-1 NMR, MS and elemental analysis. The plant-growth regulatory activities of these compounds were evaluated. The primary bioassay results indicated that these target compounds exhibited promising plant-growth regulatory activities. (C) 2009 Jian Xin Fang.
