Application of phenanthridine compounds to pesticides
-
Paragraph 0020; 0025, (2019/10/01)
The invention relates to an application of phenanthridine compounds shown in general formula (1) to pesticides. Part of the compounds is used as a plant virus agent and can well inhibit the tobacco mosaic virus; when used as a bactericide, the compounds have good inhibitory activity on tomato early blight, wheat scab, potato late blight, phytophthora capsici, rape sclerotinia rot, cucumber gray mould, rice sheath blight disease, cucumber fusarium wilt, cercospora brown spot of peanut, apple ring rot, wheat sharp eyespot, corn southern leaf blight, watermelon anthracnose and rice bakanae disease; when used as an insecticide, the compounds have poisonous activity on armyworms, mosquito larvae, cotton bollworms, ostrinia nubilalis, aphids, adult mites and plutella xylostella. In the formula,when molecular nitrogen is not imine, R can represent hydrogen atoms, methyl, acetyl and benzoyl; R and R represent a hydrogen atom or an oxygen atom simultaneously; R and R can represent hydroxyl, acetoxyl, methoxyl, methyleneoxy, a fluorine atom and the hydrogen atom; R is a bromine atom or the fluorine atom; R is the hydrogen atom or vinyl. When nitrogen is imine, R doesnot represent any group; one of R and R does not represent any group, and the other can represent the hydrogen atom, methoxyl, ethyoxyl, benzyloxy and a chlorine atom; R, R, R and Rrepresent the hydrogen atom.

The synthesis of triphaeridine and norchelerythrine through palladium-catalyzed aryl-aryl coupling reactions was studied. The secondary amides were synthesized from 6-bromopiperonylicacid and aniline, and from piperonylic acid and 2-iodoaniline respectively, and were methoxymethylated for the preparation of starting materials for the cyclization reaction. All experiments were carried out in an argon atmosphere and the extract was washed with brine. The nuclear magnetic resonance (NMR) spectral data showed the presence of singlet signals due to aromatic proton in the products.
