- METHODS AND COMPOUNDS FOR RESTORING MUTANT p53 FUNCTION
-
Mutations in oncogenes and tumor suppressors contribute to the development and progression of cancer. The present disclosure describes compounds and methods to recover wild-type function to p53 mutants. The compounds of the present invention can bind to mutant p53 and restore the ability of the p53 mutant to bind DNA and activate downstream effectors involved in tumor suppression. The disclosed compounds can be used to reduce the progression of cancers that contain a p53 mutation.

- Preparation method of trifluoromethylamine
-
The invention relates to a preparation method of trifluoromethylamine. The method includes the following steps that aromatic amine shown in the formula (1) and a trifluoromethyl reagent shown in the formula (2) react in a solvent under the condition that an alkali and/or nickel compound exists, and the trifluoromethylamine compound shown in the formula (3) is generated. According to the preparation method of trifluoromethylamine, aromatic amine and 1-trifluoromethyl-1,2-iodobenzoyl-3(H)-ketone serve as raw materials and react under the condition that the alkali and/or nickel compound exists through the amino positioning effect on aromatic nucleus. The synthesis steps of the method are simple, the cost of the raw materials is low, the production cost of trifluoromethylamine can be greatly reduced, and large-scale industrialized production is promoted.

- Nickel-Catalyzed Direct C-H Trifluoromethylation of Free Anilines with Togni's Reagent
-
An efficient nickel-catalyzed C-H trifluoromethylation for the synthesis of trifluoromethylated free anilines using Togni's reagent has been developed. This approach exhibits a good functional group tolerance, good regioselectivity, and chemoselectivity under mild conditions. The newly developed economical one-step method is a better alternative to synthesize trifluoromethylated free anilines.
