electron-rich alkynes (ynol ethers) have been found to provide a highly efficient, direct route to dioxygenated seven-membered rings, a common feature of numerous natural and non-natural targets and building blocks for synthesis. The reactions proceed in high yield at roomtemperature and tolerate a broad range of functionalities. Substituted VCPs were found to react with high regioselectivity.
