Abstract

A palladium-catalyzed enantioselective carboannulation of 1,3-dienes and aryl iodides has been established by using a BINOL-based phosphoramidite ligand. This reaction proceeded via a tandem Heck-type insertion and asymmetric intramolecular Tsuji–Trost allylic alkylation, providing indane derivatives with high levels of enantioselectivity (up to >99% ee).
