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 gold(I)‐catalyzedenantioselectivedesymmetrization of 1,3‐diols was achieved by intramolecularhydroalkoxylation of allenes. The catalyst system 3‐F‐dppe(AuCl)2 /(R)‐C8‐TRIPAg proved to be specifically efficient to promote the desymmetrizing cyclization of 2‐aryl‐1,3‐diols, which have proven challenging substrates in previous reports. Multisubstituted tetrahydrofurans were prepared in good yield
