Abstract
AbstractGenerally, oxindole derivatives are biologically important molecules and valuable building blocks in organic synthesis. Herein, we report a diisobutylaluminium hydride mediated efficient one‐pot synthesis of oxindole derivatives using N‐substituted isatins with methyl or ethyl propiolates at lower temperature (−78°C) through Morita‐Baylis‐Hillman (MBH) reaction. Within a short reaction time, a wide range of N‐alkyl or N‐aryl 3‐hydroxy oxindole derivatives (MBH adducts) were easily accessed in excellent yields under mild reaction conditions.
