Abstract

The invention discloses a preparation method and bioactivity of an amino acid ester compound containing a 4-piperidyl-6-methylpyrimidine heterocyclic ring, which is used for preventing and controllingcucumber mosaic virus, and relates to a compound shown as a general formula (I) and a preparation method thereof. The invention provides the amino acid ester compound containing the 4-piperidyl-6-methylpyrimidine heterocyclic ring, which is synthesized by taking 2-amino-4-piperidyl-6-methylpyrimidine, substituted aldehyde and malonate as raw materials and p-xylene as a solvent through a microwaveone-pot method. The compound I2 provided by the invention has a relatively good inhibition effect on the cucumber mosaic virus and tobacco ralstonia solanacearum. The formula I is shown in the description.

Description

technical field [0001] The invention relates to the field of chemical technology, in particular to an amino acid ester compound containing a 4-piperidinyl-6-methylpyrimidine heterocycle, a preparation method of the compound and a method for treating cucumber mosaic virus disease and tobacco bacterial wilt Inhibitory uses. Background technique [0002] Cucumber Mosaic Virus (CMV) is a member of the brome mosaic virus family and is one of the most widely distributed, most harmful and most economically important viruses. The distribution and hazards of the virus are found in the tobacco and vegetable growing areas around the world. The infection of tobacco and vegetables leads to a decline in yield and quality, or even failure, and brings serious economic losses to agricultural production (Shen Xiaoying, Song Shuang, Luo Jing, Zhang Xin, An Derong. Anti-tobacco cucumber mosaic virus polysaccharide screening and its effect on tobacco defense enzyme activity[J]. Microbiology Jou...
