Embodiment 1

[0040] Example 1 Synthesis of N,N-diethyl-1-phenyl--β-carboline-3-amide (6a)

[0041] 1. Step A: Synthesis of 1-phenyl-1,2,3,4-tetrahydro-β-carboline-3-carboxylic acid (2)

[0042] Weigh 20.4g of L-tryptophan (0.1mol) into a three-neck flask equipped with an electric heating mantle and electric stirrer, add 100mL of glacial acetic acid and 12.25g of benzaldehyde (0.12mol) while stirring, and stir at room temperature for 15min. Raise the temperature to 80-100°C and react for 10 hours. TLC traces until the tryptophan disappears. Stop heating. Cool to room temperature and a precipitate forms. Filter and concentrate the filtrate under reduced pressure to remove excess acetic acid and water to obtain a large number of light brown flakes. , and washed with water to obtain a white product, namely 1-phenyl-1,2,3,4-tetrahydro-β-carboline-3-carboxylic acid, with a yield of 85%.

Abstract

The invention discloses a novel harmaline amide compound, a preparation method of the compound and an application of the compound in preparation of pesticides. The structural formula of the harmaline amide compound is shown as a formula (I); the structural formula is as shown in the specification, wherein in the formula (I), R1 is selected from hydrogen, methyl, phenyl, 2,4,5-trimethoxyphenyl, p-methoxyphenyl, p-trifluoromethylphenyl or p-chlorophenyl; R2 is selected from hydrogen or bromine; R3 is selected from hydrogen or ethyl; and R4 is selected from ethyl, 2-pyridyl, o-chlorophenyl, 4,6-dimethylpyrimidyl or p-trifluoromethylphenyl. The compound has good inhibitory activities on rhizoctonia solani, collectotrichum musae, grey mould germ of strawberry, fusarium oxyspirum F sp niveum and alternaria solani and has good application prospects in control of important agricultural pests. In addition, the artificial synthesis process is simple, the product purity is high, and the compound is suitable for large-scale industrial application.

Description

technical field [0001] The invention belongs to the technical field of pesticides. More specifically, it relates to a camelamide compound and its preparation method and application. Background technique [0002] Cameline is a plant from Tribulus terrestris in my country ( Peganum harmala L . ), which is a kind of β-carboline alkaloid extracted and isolated from ), which has various biological activities such as anticancer, insecticidal, bacteriostatic and antiviral, and has attracted much attention from researchers at home and abroad. In recent years, the research on salicine mainly focuses on the anti-tumor aspect, and in-depth research has been carried out on structural modification, anti-tumor structure-activity relationship, and mechanism of action ((1) Pan Qichao, et al. cancer , 1985, 4 , 192-194; (2) Cao Jun, et al. cancer , 1993, 12 , 214-216; (3) Amy M.D., et al.
