Description

One type of 5-methyl isophthalic acid, 2, the 3-thiadiazoles joins 1, the 3-4-thiadiazoles derivative

Technical field

Technical scheme of the present invention relates to and contains the 1,2-diazole compound, is specifically related to the 5-methyl isophthalic acid, and 2, the 3-thiadiazoles joins 1, the 3-4-thiadiazoles derivative.

Background technology

1, the 3-4-thiadiazoles is because of contain N, S heteroatoms simultaneously in the heterocycle molecule; Can therefore show wide biological activity (Liu Hanwen, organic chemistry simultaneously as participating in vital movement for body and acceptor; 20012,32,1332.); Particularly at pesticide field, more for example 1, the 3-4-thiadiazole compound is showed desinsection, sterilization, weeding and plant growth regulating activity preferably.No matter bis-heterocyclic compounds also becomes an important research direction at field of medicaments or at pesticide field.In same molecule, introduce two or more heterocyclic actives center, can change the electronic structure characteristics of fractionated molecule more flexibly, improve the biological activity of molecule; Thereby it is better to obtain activity, the compound that using value is higher (Sun Yanrong, organic chemistry; 2008,28,151.).Two heterocyclic synthesis strategies mainly contain with two different heterocycle minor structure direct splicing together; On existing heterocyclic basis one by one, utilize cyclization to synthesize the another one heterocycle.Utilizing the cyclization under acidic conditions of aroyl lsothiocyanates is to synthesize 1, and the concrete method of the classical way of 3-4-thiadiazoles (Hassan, M.A.Arch.Pharm.Pharm.Med.Chem.1998 331,385.) has POCl ₃System, H ₂SO ₄/ ethanol system, H ₂SO ₄Bodies etc. are compared H with other cyclisation system ₂SO4/CH ₃The OH system has advantages such as reaction conditions is gentle, simple to operate, productive rate is higher, purification of products is convenient.1,2, the 3-thiadiazole compound has wide biological activity equally, and relevant patent and document are summed up and seen Bakulev, et al.Newyork:John Wiley&Sons; Inc, 2004 monograph, the research of relevant thiadiazoles mainly concentrates on 1,3; 4-thiadiazoles derivative, 1,2,5-thiadiazoles derivative and 1,2; On the 4-thiadiazoles derivative, and for 1,2, the active research report of 3-thiadiazoles derivative is but less relatively.1,2,3-thiadiazoles derivative commercial kind in medicine and agricultural chemicals is few, and agriculture field is used has only cotton defoliant--the clever (N-phenyl-N '-1 of disleave; 2,3-thiadiazoles-5-urea, TDZ), plant activator--Acibenzolar (phendioxin, 2; 3-thiadiazoles-7-thiocarboxylic acid methyl esters, BTH), rice field sterilant--tiadinil (3 '-chloro-4,4 '-dimethyl--1; 2,3-thiadiazoles-5-formylaniline, TDL).Contriver's research and design in earlier stage is synthetic and found that the first thiophene lures the inducing anti-disease activity of amine, at present just in the industrialization development process.In order to seek 1,2 of more high biological activities, 3-thiadiazole new compound; The present invention is 1,2, and 3-thiadiazoles ring is introduced two keys outward; One type of 5-methyl isophthalic acid has been synthesized in design, and 2, the 3-thiadiazoles joins 1; The 3-4-thiadiazoles derivative, and carried out the bioactive screening of system, in the hope of the candidate compound being provided for novel pesticide initiative research.
