  Synthesis, Fungicidal Activity, and Structure−Activity Relationship of Spiro-Compounds Containing Macrolactam (Macrolactone) and Thiadiazoline Rings

  摘要：

  Two series of novel spiro-compounds containing macrolactam or macrolactone and thiadiazoline rings, 1-thia-2-alkylimino-3,4,9-triaza-10-oxospiro[4.15]eicosyl-3-ene (4F) and 1-thia-2-alkylimino-3,4-diaza-9-oxa-10-oxospiro[4.15]eicosyl-3-ene (4G), were synthesized from 12-oxo-1,15-pentade-caniactam and 12-oxo-1,15-pentadecanlactone, respectively. Their structures were confirmed by elemental analysis, H-1 NMR, and C-13 NMR. The conformation of compounds 4F was determined via the crystal structure of a representative compound (4F(6)). The bioassay showed that compounds 4F have much better fungicidal activity against five fungi (Botrytis cinerea Pers., Sclerotinia sclerotiorum, Rhizoctonia solani Kuhn., Phomopsis asparagi Sacc., and Pyricularia oryzae Cav.) than compounds 4G. The fact above showed that the presence of a hydrogen-bonding donor for the fungicidal activity of macrocyclic compounds is very important. 4F6 showed excellent fungicidal activity against P. oryzae, which is much better than the commercial fungicide isoprothiolane, and 4F(13) showed excellent fungicidal activity against P. oryzae and good fungicidal activity against P. asparagi.
