Arene Cyanation via Cation-Radical Accelerated-Nucleophilic Aromatic Substitution
Holmberg-Douglas, Natalie,Nicewicz, David A.
supporting information, p. 7114 - 7118 (2019/09/07)
Herein we describe a cation radical-accelerated-nucleophilic aromatic substitution (CRA-SNAr) of alkoxy arenes utilizing a highly oxidizing acridinium photoredox catalyst and acetone cyanohydrin, an inexpensive and commercially available cyanide source. This cyanation is selective for carbon-oxygen (C-O) bond functionalization and is applicable to a range of methoxyarenes and dimethoxyarenes. Furthermore, computational studies provide a model for predicting regioselectivity and chemoselectivity in competitive C-H and C-O cyanation of methoxyarene cation radicals.

A series of 5-(4-(pyridin-4-yl)-1H-1,2,3-triazol-1-yl)benzonitrile derivatives (1a–p) was designed, synthesized, and identified as xanthine oxidase inhibitors with micromolar level potencies. Among them, the most promising compounds 1j and 1k were obtained with IC50 values of 8.1 and 6.7?μm, respectively. The Lineweaver–Burk plot revealed that compound 1k acted as a mixed-type xanthine oxidase inhibitor. SAR analysis revealed that a carbon atom occupying the X3 position is not as effective as a nitrogen atom, and an iso-pentyloxy or a cyclopentyloxy at the 2-position of benzonitrile moiety will benefit the inhibitory potency. The basis of xanthine oxidase inhibition by 1k was rationalized by molecular modeling studies.

The invention relates to a 1-substituted phenyl-1H-1,2,3-triazole compound, in particular to a compound applicable to preparation of anti-gout drugs and a preparation method of the compound, and belongs to the field of medicines. The compound is as shown in the general formula, wherein each R1 is independent alkyl of 1-10 carbons, 3-10 carbon atom naphthenic bases, allyl, methoxy ethyl, benzyl and substituted benzyl; substituted benzyl can be p-halogenated benzyl, p-cyano benzyl and p-alkoxy benzyl; each R2 is independent H or methyl; each R3 is independent H or ethyl. Experimental results show that the compound has a good effect in the in-vitro xanthine oxidase inhibition activity test.
