A series of 3-thiolated β-lactams were synthesized by [2+2] ketene-imine cycloaddition reaction from S-substituted mercaptoacetic acids and Schiff bases. Then, some of the 3-methylthio β-lactams were converted to 3-(methylsulfinyl) β-lactams and 3-(methylsulfonyl) β-lactams using m-CPBA under different reaction conditions. All the compounds were characterized by spectral data and elemental analyses and were evaluated for their in vitro antibacterial and antifungal activities against pathogenic strains including Staphylococcus aureus (Methicillin resistant strain). The preliminary screening results indicated that some of these compounds demonstrated moderate to very good antibacterial and antifungal activities.

Bu3SnH-mediated aryl radical cyclisations of a range of N-vinylic 2-iodobenzamides 10 were examined. The enamides 10a-d gave exclusively the 5-exo cyclisation products 11a-d, whereas the enamides 10e,f having a phenyl substituent on the vinylic carbon ato
Dicoordinated Phosphorus Compounds: a Novel 4,5-Disubstituted 1,2,3,4-Triazaphosphole. X-Ray Molecular Structures of a 2-N-BF3 Complex of 4,5-Diisopropyl-1,2,3,4-triazaphosphole and of its Tetramer. Conformation in the Crystalline Form and in Solution
