- Quinoline and 2-nitroimino-1, 3-diazacycloalkane hybrids: Design, synthesis and insecticidal activity
-
A library of new hybrid molecules comprising quinoline, 2-nitroimino-1, 3-diazacycloalkane motifs were designed and synthesized as plausible neonicotinoid analogues. These compounds were synthesized from 2-chloro/aryloxy-3-formyl quinolines and guanidine nitrate with the coupling of 2-chloro/aryloxy-3-(chloromethyl)quinolines, 2-nitroimino-1, 3-diazacycloalkanes under phase transfer catalysis (PTC) as crucial step. All the compounds were obtained in excellent yields (80–90%) and were characterized by 1H, 13C NMR and mass spectrometry. The newly generated compounds were screened for insecticidal activity against aphids in safflower field and some of them displayed moderate activity.

- Synthesis of 2-nitroimino-1,3-diazacycloalkanes
-
An efficient, practical and enviro-friendly method of preparation of 2-nitroimino-1,3-diazacycloalkanes 3a-d has been reported by a simple reaction between nitroguanidine 1 and diamines 2a-d in the presence of conc. HCl in aq. medium with very good yields.
