This research demonstrates the synthesis of oxindole spirohydropyridine derivatives from enaminone and diazo oxindole, suggesting new pathways for compound development.
Presented herein is a concise and divergent synthesis of oxindole spirohydropyridine derivatives based on the reaction of enaminone with diazo oxindole. In forming the hydropyridine skeleton, one enaminone acts as...
