2. Scheme 1 Organic Synthesis of Indole Alkaloids
(A) Photoredox catalysis generates a N-centered radical that forms a 2c-3e bond after initial cyclization.
(B) Stereoelectronic assistance in the key radical intermediate and the two paths for the radical cascade.
(C) The variations in the intra- and intermolecular radical reactions that follow the initial C–N bond formation are the key to the diversity of natural products obtained by Qin and coworkers.
