Synthesis and Herbicidal Activities of N-(1-Carbomethoxy)-ethyl-N-[5-(2-chloropyrid-4-yl)-1,3,4-thiodiazol-2-yl] Amides
In order to investigate the structure-activity relationship and improve the activity of (herbicidal) lead compound 2-sec-butylamino-5-(2-chloropyrid-4-yl)-1,3,4-thiodiazole (BCPT) which was found in
The Advance on Total Synthesis of Rocaglamide
The advance on total synthesis of rocaglamide,a natural anticancer and insecticidal agent,was reviewed with eighteen references.The stereochemical characteristics of every synthetic pathway were also
The research on selective synthesis of keto-isophorone
In this paper,the selective ketalization of keto-isophorone and diols was reported.The effects of reaction conditions such as reaction temperature,reaction time,the quantity of catalyst and molar
Total synthesis of natural product(E)-4′-methoxy-3,5-dihydroxy-stilbene
Starting from 3,5-dihydroxy benzoic acid,3,5-diacetoxy benzoic acid chloride was synthesized via acetoxy protection and chloridation,then through Heck reaction with p-methoxy styrene and deacetoxy
New Pesticides Reported in XVI International Plant Protection Congress (Glasgow)
Eight new synthetic pesticides,including three fungicides and five insecticides,which were reported in XVI international plant protection congress (Glasgow) are briefly introduced in this paper.
Studies on Pyridine Derivatives(X):Synthesis and Herbicidal Activity of 2-sec-Butylamino-5-(2-aryloylpyrid-4-yl)-1,3,4-thiodiazoles
2-sec-Butylamino-5-(2-chloropyrid-4-yl)-1,3,4-thiodiazole(BCPT) is a herbicidal leading compound.In order to improve its herbicidal activity and study the relationship between chemical structure and
Studies on pyridine derivatives (VIII):Synthesis and bioactivity of 2-alkylamino-5-(2-aryloylpyrid-3-yl)-1,3,4-thiodiazoles
Fourteen novel title compounds were synthesized from 2-substituted phenoxy isonicotinyl hydrazide with isothiocyanate.The structures of the compounds were confirmed by 1H NMR,IR and elemental
