N′-Nitro-2-hydrocarbylidenehydrazinecarboximidamides and methoxyacrylates are two types of important agrochemicals. By combining their key fragments into one framework, a series of the title compounds was designed and synthesized. Some of these compounds have shown excellent insecticidal activities for aphides, for example, the LC50 values of compounds 6-06, 6-11 and 6-19 against M. perslcae and H. amygdale were found to be 1.9/14.4, 13.4/1.5 and 0.3/38.4 mg L-1 respectively. They were also effective against the mycelium growth of B. cinerea in vitro. Compound 6-04 could control (～100%) cucumber anthrax and rice blast at 100 mg L-1 in vivo, and inhibit the spore germination (～100%) of vegetable gray mold at 6.25 mg L-1. These compounds could be considered as potential insecticidal or fungicidal candidates for crop protection. The results of structure-activity relationship (SAR) studies are discussed.

A novel series of acyclic imine-substituted nitenpyram analogues were designed and synthesized from nitroaminoguanidine, and their structures were confirmed using X-ray diffraction crystallography. Preliminary bioassays showed that the target molecules exhibited good activities against aphids in laboratory (Myzus persicae Sulzer) and field trials (M. persicae Sulzer and Brevicoryne brassicae Linnaeus). Comparative molecular field analysis and comparative molecular similarity indices analysis were employed to develop a three-dimensional quantitative structure-activity relationship model that describes the insecticidal activity of 21 neonicotinoid derivatives. Simple synthesis, low cost, and good insecticidal activity have made this series of compounds become very promising candidates for future commercial pesticides.
