摘要
A series of novel pyridine-annelated spirooxindole-3,2'-pyrrolidines was prepared via 1,3-cycloaddition reaction involving N-methylmaleimide as 1,3-dipolarophile and the appropriate azomethine ylide. The latter 1,3-dipolar species were generated in situ via decarboxylative condensation reaction of the particular alpha-amino acid with pyridine-annelated isatin in aqueous methanol under reflux. The structures of these new spirooxindole cycloadducts are based on microanalytical, spectral (IR, HRMS, and NMR), and X-ray crystal data.
