Embodiment 1

[0045] Embodiment 1: the preparation of compound 1

[0046] (1) At room temperature, under nitrogen protection, 21.43g (0.06mol) Ph 3 PMeBr and THF 250ml, the reaction system was cooled to 0°C, 3.4gNaH (70%, 0.1mol) was added to the reaction system, stirred at room temperature for 30min, and 7.1g (0.05mol), GC monitors the reaction, after the reaction is complete, filter and distill the filtrate, steam THF first, and then distill under reduced pressure (120°C, 50mmHg) to obtain a colorless and transparent oily liquid product 2.5g, purity 90%, yield 35%. GC: tR = 6.626 min, 90%.

[0047] (2) Under ice-bath conditions, add KOH (58.35g, 1.16eq, 1.04mol) and 585ml of water to a 1000ml three-necked flask successively, cool the reaction system to 0°C, and dropwise add (103.61g, 1eq, 0.892mol), after the dropwise addition, stir at room temperature for 24h; cool the reaction system to 0°C again, and add NaNO 2 (71.76g, 1.16eq, 1.04mol), the reaction system was kept at 0°C, and ...

Abstract

The invention relates to the field of agricultural plant protection, and particularly relates to a sterilization compound and a preparation method and an application thereof. The compound has the structure represented by a formula defined in the specification, wherein R is selected from one of components defined in the specification; the compound has excellent bacteriostatic activity on potato phytophthora infestans, phytophthora capsici, phytophthora nicotianae, peronophthora litchii, pseudoperonospora cubensis and other plant pathogenic oomycetes, and has broad application prospects in prevention and control of oomycete diseases.

Description

technical field [0001] The invention relates to the field of agricultural plant protection, in particular to a bactericidal compound, a preparation method and an application thereof. Background technique [0002] Phytopathogenic oomycetes can cause very serious diseases to most crops, natural plants and ornamental plants, including more than 50 types of Phytophthora that are the most harmful to plants, and they can cause most important economic crops such as potatoes, tomatoes, Severe losses in chilli, soybean and tobacco production, as well as damage to agro-ecosystems. [0003] The most typical plant pathogen is Phytophthora infestans (Pytophthora infestans), which can cause late blight on potatoes and tomatoes, causing serious losses in agricultural production, and the resulting Irish famine is well known. The International Potato Center estimates that the annual loss due to late blight is about US$3 billion, and the emergence of serious resistance problems in North Amer...
