This study demonstrates a highly efficient regiodivergent ligand-controlled palladium-catalyzed cycloaddition reaction of vinyloxazolidine-2,4-diones with 1,3,5-triazinanes. In the presence diphosphine ligand, proceeds via (5+2) pathway to afford 1,3-diazepin-4-ones in excellent yields, while using monophosphine smoothly (3+2) give imidazolidin-4-ones good yields.
