With the goal of searching for new potential nematicides with high activity and low toxicity, new molecules are needed as potential prototypes for the synthesis of new nematicidal compounds. A series of novel diamides based on diphenylacetylene scaffold were designed and synthesised. The conformation of the amide was restricted through the ten-membered H-bonded ring. Their structures were characterised by 1H NMR, 13C NMR, 19F NMR, and high-resolution mass spectrometry. The preliminary bioassays evaluated against Meloidogyne Incognita indicated that most of the title compounds were endowed with moderate-to-good activities at the concentration of 25mgL-1. In particular, compounds 9a, 9c, 9g, 9h, 9k, and 9l displayed >50% nematicidal activity at 5mgL-1. It is possible that the novel diamides with diphenylacetylene scaffold, which possess good nematicidal activities, provide distinct nematicidal chemotypes that can be used as leads for further optimisation.

The synthesis of furo- and thienopyridones 13a,b as well as the corresponding pyrroles 14a,b by using the 1,7-dipolar cyclization route of conjugated nitrones 9a,b is reported.In the presence of O2 and light thy pyridones are converted into the pyridinediones 17a,b.
