Organocatalytic Michael addition of 2-nitro methylene imidazolidines to α,β-unsaturated aldehydes: Concise synthesis of chiral insecticide Paichongding

An organocatalytic Michael reaction of 2-nitro methylene imidazolidines to α,β-unsaturated aldehydes followed by acetal-amination affords hexahydroimidazo[1,2-a]pyridines in high yields and with moderate to excellent enantioselectivity. The utility of the reaction was illustrated by a one-step transformation to Paichongding, an insecticide of the neonicotinoid family.

PREPARATION METHOD AND USE OF COMPOUNDS HAVING HIGH INSECTICIDAL ACTIVITIES

The present invention discloses a kind of nitromethylene derivatives as well as their preparation method and their uses. The insecticidal activity tests show that the nitromethylene derivatives of the present invention not only show high insecticidal activities against insects with piercing-sucking type or scratching type mouthparts, such as aphid, leafhopper, plant hopper, thrips and white fly and their resistant strains, but also show high insecticidal activities against Lissorhoptrus oryzophilus, carmine spider mite, and they can also be used to prevent sanitary pest, and white ant.

cis-Nitromethylene neonicotinoids as new nicotinic family: Synthesis, structural diversity, and insecticidal evaluation of hexahydroimidazo[1,2-α]pyridine

A series of neonicotinoids analogues of hexahydroimidazo[1,2-α]pyridine were modified at 5-, 6-, and 7-positions, and their insecticidal activities were evaluated. Introducing a methyl or ethyl at 7-position increased the insecticidal activities, while ot
