  Anti-mycobacterial 4-hydroxy-3-phenylpyridin-2 (1H)-ones

  摘要：

  4-Hydroxy-3-phenylpyridin-2 (1H)-ones with different substituents either at N-1 or in the phenyl group were synthesized by reaction of ethyl-beta-aminocrotonates with dialkyl malonates or 'magic malonates' (2,4,6-trichlorophenyl malonates). The evaluation of these compounds on Mycobacterium tuberculosis H37Ra, Escherichia coli B and Staphylococcus aureus ATCC 25923 showed significant inhibitory effects on M tuberculosis (5g and 5s, MIC = 8-mu-g/ml). A structure-activity relationship is discussed.

  A general and catalytic α-arylation of cyclic 1,3-dicarbonyls have been developed, providing expedient access toward a wide range of high-value 2-aryl (hetero)cyclic 1,3-dicarbonyls. The key to success is through a cyclic iodonium ylide strategy. Our approach is base-free and exhibits broad substrate scope (>100 examples). Importantly, our approach allows late-stage modification and significantly simplifying
