One-pot four component domino strategy for the synthesis of novel spirooxindole pyrrolizine linked 1,2,3-triazoles via stereo- and regioselective [3 + 2] cycloaddition reaction in acidic medium

An efficient, one-pot four component condensation has been reported for the synthesis of spirooxindole pyrrolizine linked 1,2,3-triazoles via [3 + 2] cycloaddition. The structures were confirmed by 1 H NMR, 13 C NMR, mass spectra and X-ray.
