Synthesis and nematicidal activities of 1,2,3-benzotriazin-4-one derivatives containing thiourea and acylthiourea against Meloidogyne incognita
摘要:
Two series of novel 1,2,3-benzotriazin-4-one derivatives containing thiourea and acylthiourea were designed and synthesized. The bioassay results showed that most of the test compounds showed good nematicidal activity against M. incognita at the concentration of 10.0 mg L-1 in vivo. The compounds A13, A17 and B3 showed excellent nematicidal activity on the second stage juveniles of the root-knot nematode with the inhibition rate of 51.3%, 58.3% and 51.3% at the concentration of 1.0 mg L-1 respectively. It suggested that the structure of 1,2,3-benzotriazin-4-one derivatives containing thiourea and acylthiourea could be optimized further. (C) 2016 Elsevier Ltd. All rights reserved.

One-pot, three-component condensation of aroylthiourea, primary amine and alpha-halocarbonyl derivatives for the synthesis of 2-acylimino-3-alkyl-3H-thiazoline derivatives is described. This method is useful for simultaneousiv incorporating diverse functional groups at four positions in the 3H-thiazoline skeleton to obtain beta-turn tripeptide mimics. (C) 2004 Elsevier Ltd.
