In this paper, Pd-catalyzed [4+2] decarboxylative cycloaddition of 4-vinylbenzodioxinones with barbiturate-derived alkenes has been developed, leading to various spirobarbiturate−chromane derivatives in high yields with excellent diastereo- and enantioselectivities. The scale-up reaction and further derivation of the product were demonstrated. A plausible reaction mechanism was also proposed.
