Oxoindolines are interesting heterocyclic
compounds which show diverse biological significance. In
this oxoindolines was prepared by one-pot condensation
reaction of isatin, dimedone, and various active methylene
using piperidine as a basic catalyst and solvent as methanol,
under stirring at ambient temperature. The final products
were characterized by FT-IR spectroscopy, Massspectroscopy, 1H NMR-spectroscopy and 13C NMRspectroscopy.
