The invention discloses a homopiperony lamine compound which has a structural general formula I as follows as shown in the specification:
wherein definitions of substituents in the formula are as shown in the specification. The compound shown as the general formula I has broad-spectrum bactericidal and insecticidal activity in the field of agriculture. The compound shown as the general formula I has a good prevention effect on various germs such as cucumber downy mildew, wheat powdery mildew,
puccinia sorghi,
rice blast and cucumber gray mold, and particularly, still has the good prevention and control effect on the cucumber downy mildew, the
puccinia sorghi
and the wheat powdery mildew at a lower dosage. At the same time, a part of compound has better insecticidal activity, and can be used for preventing and controlling various insect pests such as diamondback moths,
myzus persicae,
armyworms and
tetranychus cinabarinus
boisdu.
direct reductive N‐functionalization of aliphatic nitro compounds is presented. The nitro group is partially reduced to a nitrenoid, with a mild and readily available combination of B2pin2 and zinc organyls. Thereby, the formation of an unstable nitroso intermediate is avoided, which has so far severely limited reductive transformations of aliphatic nitro compounds. The reaction is concluded by an electrophilic
