Dibromo-2-pyrone underwent facile Diels-Alder [4+2] cycloadditions with cycloalkenyl silyl ethers to provide a series of tricyclolactones, with good to excellent chemical yields and stereoselectivity. The resulting cycloadducts could be readily converted into the corresponding bicarbocycles upon sel
