| Popis: | A simple sulfinylated cascade transformation has remained largely underexplored. Herein, we disclose a detail and unified strategy of BF3.Et2O promoted cascade addition/dearomatization spiro-cyclization of biaryl ynones with aryl sulfinic acid. This approach provides a wide variety of functionalized spirotrienones in mild conditions and moderate to high yield at room temperature. A detailed mechanistic study has been carried out to prove cationic process. |
