- Preparation method of chlorenone
-
The invention relates to a preparation method of chlorenone. The chlorenone is prepared from 3, 3-dimethyl-1-(1H-1, 2, 4-triazole-1-yl) butane-2-one and p-chlorobenzyl chloride as raw materials through reaction, the reaction is carried out in the presence of a solvent, a catalyst and alkali, and the solvent is one or more of cyclohexane, isopropanol, n-butyl alcohol, toluene, methylcyclohexane andn-hexane. The method is relatively safe in process, simple to operate, low in cost, relatively high in target product content and yield, less in three wastes and suitable for industrial production.

- New lead compounds for brassinosteroid biosynthesis inhibitors
-
The first brassinosteroid biosynthesis inhibitor is reported. Among newly synthesized triazole derivatives, 4-(4-chlorophenyl)-2-phenyl-3- (1,2,4-triazoyl)butan-2-ol (6) was found to inhibit the growth of cress seedlings, and this inhibition was recovered by the treatment of brassinolide, suggesting that compound 6 primarily inhibits brassinosteroid biosynthesis.

- Fungicidal hydroxyalkinyl-azolyl derivatives
-
Hydroxyalkinyl-azolyl derivatives of the formula STR1 in which A is a nitrogen atom or the CH group, R is optionally substituted alkyl, cycloalkyl or phenyl, R1 is hydrogen, alkyl, alkenyl, alkinyl, or optionally substituted benzyl, R2 is hydrogen or methyl, and X is hydrogen, bromine or iodine, or addition products thereof with acids or metal salts exhibit fungicidal activity. Some intermediates therefor are also new.
