trifluoromethylation of aryl-substituted cyclopropanols via a radical ring-opening pathway is reported herein, which provides an easy and straightforward access to structurally diverse β-CF3 ketones in good yields and excellent enantioselectivities under very mild conditions. Critical to the success of the copper-catalyzed radical relay is that a benzylic radical intermediate can be enantioselectively trapped by

Tetrahydrobenzo[b]azepines (THBAs) are commonly found in many bioactive compounds; however, the modular preparation of functionalized THBAs remains challenging to date. Here, we report a straightforward method to synthesize THBAs directly from simple aryl iodides via palladium/norbornene (Pd/NBE) cooperative catalysis.
