Selective Access to Dihydrophenanthridines and Phenanthridinones Via Cyclisation of Aryl Amines Onto N-tethered Arynes.
Chemical communications(2023)
摘要
5,6-Dihydrophenanthridines are prepared from aryl amines via intramolecular addition to N-tethered arynes under mild conditions. A new o-silylaryl triflate precursor was developed to increase reactivity and enable electron-rich and electron-poor aryl amines to undergo cyclisation. A complete switch in product selectivity occurs when the reaction is conducted in air, affording the corresponding phenanthridin-6(5H)-one as the sole product under otherwise identical reaction conditions.
