Synthesis of Oxindoles by Tandem Heck-Reduction-Cyclization (HRC) from a Single Bifunctional, in Situ Generated Pd/C Catalyst
摘要:
A tandem sequence involving palladium-catalyzed sequential Heck-reduction-cyclization transformations in mild conditions has been developed for the synthesis of oxindoles. The protocol involves inexpensive reagents and does not require any additives such as base or ligands.
