We herein report a robust and safe palladium catalyzed domino-carbonylation/Suzuki–Miyaura cross-coupling reaction of vinyltosylates with arylboronic acids using Mo(CO)6 as CO-source. The derived γ-keto ester were subsequently cyclized under acidic conditions to obtain γ-hydroxybutenolides, an important structural motif, which occurs in biologically active natural products.
