Definitions
- the invention belongs to a fine chemical pesticide herbicide.
- the purpose of the present invention is to develop a highly effective pesticide herbicide.
- the present invention is a phthalimide herbicide, and the biggest feature of its structure lies in-
- the 1-position on the benzene ring is connected to the heterocyclic ring.
- the 5-position on the benzene ring may be substituted by methyl thioacetate, cyclopentyloxy, allyloxy, methallyloxy, ethyl 2-chloropropionate, etc.
- Benzofuran is formed at the 6-position of the benzene ring.
- the invention synthesizes six new highly effective herbicides, and their structures are:
- the compound of the present invention is synthesized as follows:
- the ratio of the raw material aniline to methyl acrylate is 1:20, and the reaction is performed in acetonitrile in the presence of copper chloride, and the product (B ′) is hydrolyzed to produce the product (C ′) under acidic conditions.
- This step is carried out in three steps:
- Compound II was prepared in the same manner as above, with a melting point of 150 to 151 ° C. The structure was confirmed by H-NMR.
- Compound III was prepared in the same manner as above, with a melting point of 128 to 135 ° C, and its structure was confirmed by H-NMR.
- Compound IV was prepared in the same manner as above, with a melting point of 154 ⁇ 155 ° C, and the structure was confirmed by H-NM.
- Compound V was prepared in the same manner as above, with a melting point of 101 to 104 ° C, and its structure was confirmed by H-NMR.
- Compound VI was prepared in the same manner as above, with a melting point of 139 to 140 ° C. The structure was confirmed by H-NMR.
