units in natural products and medicinal molecules, and methods for their introduction are of fundamental importance. Here we report one-pot cycloadditions of ethynyl indoloxazolidones with 1,3-cyclohexanediones enabled by copper catalysis, leading to a series of functionalized furan derivatives in good yields. This method features mild reaction conditions, high efficiency, and wide substrate scope
