Study on Regioselective Three Component Domino Synthesis of Polyhydrospiro [indoline-3,3’-pyrrolizine]-2-one via [3+2] Cycloaddition Reaction under Ultrasonic-Irradiation

Due to its interesting structure and biological significance, Spiro compounds with attached indole moiety having an all-carbon quaternary stereogenic core have attracted synthetic organic chemists. In present work we have reported synthesis and characterisation of novel Hexahydrospiro [indoline-3,3′-pyrrolizine]-2-one derivatives in good to excellent yields through [3+2] cycloaddtion reaction in regioselective manner under ultrasonic irradiation. Via…
