-
, (2020/05/08)
The invention discloses a method for preparing 2, 5-dimethylphenylacetyl chloride, and belongs to the field of pesticide intermediate synthesis. According to the method, p-xylene is used as an initialraw material, chloromethylation, cyaniding, hydrolysis and acylating chlorination are carried out, 2, 5-dimethylphenylacetyl chloride is obtained after continuous reaction without purification, the total yield of the four steps of reaction is 75%, and the product purity is greater than 99.0%. The method is simple in process and only needs to purify the final product and is low in operation cost,mild in reaction condition and high in yield and product purity and is very easy to realize industrial production.

LIGAND-ENABLED META-C-H ACTIVATION USING A TRANSIENT MEDIATOR
-
Page/Page column 94; 95, (2016/08/23)
An alternative approach to formation of a C-C bond at a meta-position of an aromatic compound is disclosed that employs an ethylenically unsaturated bicyclic compound as a transient mediator to achieve meta-selective C-H activation with a simple and common ortho-directing group. The use of a pyridine-based ligand assists in relaying the palladium catalyst to the meta-position by the unsaturated bicyclic compound following initial ortho-C-H activation.

New drugs for neglected tropical diseases such as human African trypanosomiasis (HAT) are needed, yet drug discovery efforts are not often focused on this area due to cost. Target repurposing, achieved by the matching of essential parasite enzymes to those human enzymes that have been successfully inhibited by small molecule drugs, provides an attractive means by which new drug optimization programs can be pragmatically initiated. In this report we describe our results in repurposing an established class of human Aurora kinase inhibitors, typified by danusertib (1), which we have observed to be an inhibitor of trypanosomal Aurora kinase 1 (TbAUK1) and effective in parasite killing in vitro. Informed by homology modeling and docking, a series of analogs of 1 were prepared that explored the scope of the chemotype and provided a nearly 25-fold improvement in cellular selectivity for parasite cells over human cells.
