New and convenient approach for synthesis of metconazole

In terms of environmental and food supply protection, development of green, efficient, and less toxic pesticides is of great importance and in continuous demand. Metconazole, a triazole antiseptic, possesses such advantages, being environmentally friendly and high efficiency with broad-spectrum activity against bacteria and fungi. However, previously reported synthetic routes for metconazole have many disadvantages, for example, requiring multiple steps, being complicated, and suffering from high cost. We report herein a new, convenient, and high-yield four-step (aldol condensation, dimethylation, hydrogenation, and one-pot triazolation) synthesis for metconazole with relatively low cost.

Preparation method of 5,5-dimethyl-2-cyanocyclopentanone

The invention relates to a preparation method of 5,5-dimethyl-2-cyanocyclopentanone and a preparation method of a related intermediate 2,2-dimethyl-5-(4-chlorobenzyl)cyclopentanone and an application thereof to synthesis of a bactericide metconazole. Cholesteryl iso-butyrate, 1,3-dihalogenated propane, a cyanidation agent, p-chlorobenzyl chloride, and the like are used as main raw materials, multiple steps of reactions are used for preparation and separation, compared with a traditional process, the technique implementation is convenient and yield is high, and the methods have good industrial application prospects.
