Abstract

The invention discloses a dithioacetal derivative containing methoxyacrylate, a preparation method and an application thereof. The general formula is as shown in (I), wherein, Y is N or CH; R1 is a substituted halogen atom, a methyl, a methoxy, a ethoxy or a 3, 5 -dimethoxy, the halogen atom may be fluorine, chlorine, bromine; R2 is a substituted aromatic ring, a heterocyclic ring, a 1- propyl alcohol, a ethyl, a propyl, a isopropyl. The corresponding position of the aromatic ring contains a fluorine or chlorine, and the heterocyclic ring is a morphinane ring. The derivative has better activity on plant viruses such as potato Y virus, cucumber mosaic virus, tobacco mosaic virus, tomato chlorosis virus and the like, and has simple structure, simple preparation process and low production cost.

Description

technical field [0001] The present invention relates to the field of chemical technology, in particular to dithioacetal derivatives containing methoxyacrylate, and also to a method for preparing the dithioacetal derivatives containing methoxyacrylate, and the Dithioacetal derivatives containing methoxyacrylate are used to prepare and prevent potato Y virus disease, cucumber mosaic virus disease, tobacco mosaic virus disease, tomato chlorosis virus disease and southern rice black-streaked dwarf virus disease, etc. Drug application for plant virus diseases. Background technique [0002] Plant virus disease is a class of major diseases in agricultural production, known as "plant cancer", tobacco mosaic virus (TMV), cucumber mosaic virus (CMV), potato virus Y (PVY) and southern rice black-streaked dwarf Reduction virus (SRBSDV) is several important plant virus diseases, they can infect almost all vegetables, such as cucumber, tomato, potato, zucchini, etc., and bring very ser...
