Abstract:A new three-component radical cascade process has been proposed for the synthesis of 3-organoselenyl chromones from 2-methoxyaryl alkynones, Se powder and organic boronic acids.
Herein, we report a general and sustainable electrochemically promoted oxidative selenocyclization protocol for the synthesis of organoselenyl isoxazoles from 2-alkyn-1-one O-methyloximes and diorganyl diselenides.
