Paragraph 0072; 0076; 0079, (2020/05/08)
The invention discloses a bis-(p-alkoxy benzene acrylketone) like glutathione-S-transferase potential inhibitor. Structure and living features of the potential inhibitor are as follows: two p-alkoxy benzene acrylketone units are linked to two amino groups, alcoholic hydroxyl groups and carboxyl groups or one amino group and one alcoholic hydroxyl group which are spaced by less than 8 single bonds through amide and/or ester bond, wherein compounds obtained are substrate and inhibitor of glutathione-S-transferase, namely GST; the GST catalyzes carbon-carbon bond and reduced glutathione, namely GSH, of alpha, beta-unsaturated ketone of each p-alkoxy benzene acrylketone unit in the compounds and generates a compound, namely product, through Michael addition. The product shows a stronger inhibiting efficacy on the GST, so that the compound is a GST potential inhibitor; the product has a stronger inhibiting efficacy on human GST isozyme mu in comparison with human GST isozyme alpha and pi; and the compounds can enter into cells, and can enhance inhibiting effect of cis-platinum on drug-resistant carcinoma cell growth.

(Chemical Equation Presented) Although nitrogen-containing group-directed cyclopalladation reactions have been well-known, Pd(II) insertion into C-H bonds promoted by coordination of an oxygen-only group to the palladium remains rather rare. In the present study, the first cyclopalladation complex formed from a simple phenol ester was characterized by X-ray crystallography. A promising protocol for the ortho C-H activation/aryl-aryl coupling of phenol esters that was not sensitive to moisture or air was then established. The utility of the reaction was demonstrated for the synthesis of useful phenol derivatives. Copyright
Electro-organic reactions. Part 41. Diels-Alder reaction of o-quinodimethanes from the cathodic reduction of α,α'-dibromo-1,2-dialkylbenzenes

Cathodic reduction of α,α'-dibromo-1,2-dialkylbenzenes in DMF containing ET4N+ Br- as supporting electrolyte, in the presence of dienophiles (e.g. maleic anhydride derivatives), yielded Diels-Alder adducts of o-quinodimethanes. Selective reduction of the benzylic dibromides was often possible even when their irreversible cyclic voltammetric reduction peak potentials were more negative than the E(o) values for the anhydrides. This might be a consequence of redox catalysis, with the anhydrides having a dual role as mediators and dienophiles.
