Solving a Mystery with Classical and Dual Photoredox Catalysis: Application of Nickel in the Synthesis of Ergot Alkaloids.
Organic Letters May 24, 2024 Jan Brauer, Rainer Wiechert, Anika Hahn et al. 5 citations
A short synthesis of the ergot alkaloid lysergene and a formal total synthesis of lysergic acid diethylamide (LSD) under the avoidance of palladium and including two nickel-catalyzed steps instead have been developed. A key intermediate of this approach has already been reported by Hendrickson et al. in 2004 (Hendrickson, J.B. et al. Org. Lett. 2004, 6, 3-5), yet the spectral data do not match,...
