Synthesis of a series of novel spiro pyrrolidines has been accomplished by 1, 3-dipolar cycloaddition reaction of azomethine ylide generated from phenylalanine and isatin with dipolarophiles in good yield. The reaction proceeded with high regio and stereoselectivity. The products have been characterized by elemental analyses and spectroscopic techniques, namely IR, 1H NMR and 13C NMR spectroscopies. Single crystal analysis of compounds 4k 2D-NMR analysis of compound 4k confirmed the structures of spiropyrrolidine derivatives. These compounds were evaluated for their antimicrobial activity. Most of the synthetic compounds exhibited good activity against microorganisms.

Complex 5b shows the highest binding constant value. So, thermodynamic parameters of 5b‐HS DNA complex at different temperature have been evaluated. Also, Viscosity measurement and molecular modeling studies have been performed to know the binding mode of complexes. Based on the observations, an intercalative binding mode of DNA has been proposed. Further confirmation of intercalative mode of DNA binding
