Five novel sulfonamidesderivatives HR5 - HR8 and HR14 were synthesized by sulfonylation of primary or secondary amine in the presence of base through nucleophilic substitution reaction. Structural elucidation was carried out through FT-IR, UV, 1 H NMR, MS and elemental analysis. Prepared compounds were evaluated against pathogenic strains of bacteria ( S. aureus and E. coli ) and fungi ( A. flavous

5-cis-disubstituted pyrrolidines with high diastereoselectivity (up to >99:1 dr) and enantioselectivity (up to >99% ee). The overall reaction constitutes a formal 1,1-bifunctionalization of terminal alkynes, which has hitherto been reported only rarely. Additionally, this method provides efficient access to pharmaceutical intermediate and to carry out postmodification of natural products.
A series of novel N-phenylsulfonylnicotinamide derivatives (1–24) have been synthesized and evaluated as potentialEGFR tyrosine kinase (TK) inhibitors. Among all the compounds, compound 10 (5-bromo-N-(4-chlorophenylsulfonyl)nicotinamide) showed the most potent growth inhibitory activity against EGFRTK and antiproliferative activity of MCF-7 cancer cell line in vitro, with IC50 value of 0.09 and 0
