Prof. Barry M. Trost, James T. Masters and Dr. Aaron C. Burns Palladium-Catalyzed Asymmetric Allylic Alkylation of 3-Aryloxindoles with Allylidene Dipivalate: A Useful Enol Pivalate Product Angewandte Chemie International Edition 52
Triple A: The catalytic asymmetric allylic alkylation (AAA) of 3-aryloxindoles with allylidene dipivalate is described. This reaction affords stable, synthetically useful enol pivalates in high yield and with excellent regio- and enantioselectivity. A broad range of substrates is tolerated, including unprotected and 3-heteroaryl nucleophiles.
