Mishra, Vivek Kumar published the artcileC-H-Activation approach towards the core structure of the alkaloid ¦Ã-lycorane, SDS of cas: 1293990-73-4, the publication is Tetrahedron (2016), 72(41), 6499-6509, database is CAplus.
With a view towards the synthesis of lycorane-like structures several N-(pivaloyloxy)benzamides were reacted with cyclohexa-1,3-diene in presence of a rhodium(III) catalyst which resulted via C-H activation in the corresponding tetrahydrophenanthridinones, e.g., I. Subsequently, various strategies were explored to convert these tricyclic phenanthridinones to the tetracyclic core structure of the lycoranes. While radical based approaches were not successful, we were able to form ring D (pyrrolidine ring) by a nickel catalyzed reaction, resulting in alkaloid derivatives II [R = CN and H].
