5-aryl substituted 2-aminobenzoxazole derivative and preparation method and application thereof

Abstract

The invention discloses a 5-aryl substituted 2-aminobenzoxazole derivative and a preparation method and application thereof, and belongs to the technical field of pesticides, the 5-aryl substituted 2-aminobenzoxazole derivative is characterized in that the structure of the 5-aryl substituted 2-aminobenzoxazole derivative is shown as a formula (I), and R is any one of substituted or unsubstituted phenyl, five-membered and six-membered heterocyclic groups or substituted heterocyclic groups and benzothienyl; when the substituent groups are substituted phenyl groups, the substituent groups are anyone or more of hydrogen atoms, halogen, hydroxyl groups, nitryl groups, cyano groups, alkoxy groups, aldehyde groups, amino groups and C1-C6 alkyl groups; when the substituent group is a substitutedheterocyclic group, the substituent group is halogen; and according to the invention, a series of novel 5-aryl substituted 2-aminobenzoxazole derivatives are prepared, and the 5-aryl substituted 2-aminobenzoxazole derivatives are applied to prevention of plant diseases caused by plant pathogenic fungi for the first time.

Description

Technical field[0001]The invention belongs to the technical field of pesticides, and specifically relates to a 5-aryl substituted 2-aminobenzoxazole derivative, a preparation method and an application thereof.Background technique[0002]Plant diseases are natural disasters that seriously endanger agricultural production and are difficult to control. They not only cause crop yield and quality degradation, but also some pathogenic fungi will produce carcinogenic, neurotoxic or teratogenic polymorphisms during the growth and metabolism of the host. A variety of secondary metabolites (such as aflatoxin and zearalenone, etc.) seriously threaten the health and safety of humans and animals. Although the chemical fungicides that have been developed have played an important role in safeguarding agricultural production and human life, the problems of plant resistance, environmental pollution, ecological imbalance, and food safety caused by long-term dependence and large-scale use have become in...
