Photoredox catalyzed cascade CF 3 addition/chemodivergent annulations of ortho -alkenyl aryl ureas
Herein, we report a substrate-controlled cascade cyclization of -alkenyl aryl ureas, an ambident nucleophile for constructing functionalized heterocycles such as 2-amino-1,3-benzoxazines and dihydroquinazolinones in a chemodivergent fashion using photoredox catalysis under mild conditions.

Summary: | Herein, we report a substrate-controlled cascade cyclization of
-alkenyl aryl ureas, an ambident nucleophile for constructing functionalized heterocycles such as 2-amino-1,3-benzoxazines and dihydroquinazolinones in a chemodivergent fashion using photoredox catalysis under mild conditions. The versatility of the method has been successfully demonstrated by applying this strategy to a wide range of substrates and for the synthesis of functionalized etifoxine drug derivatives. |
