Kim, Se Hun published the artcileSynthesis of scalaridine A, COA of Formula: C20H28BNO5, the publication is Tetrahedron Letters (2015), 56(43), 5914-5915, database is CAplus.

A synthesis of the pyridine-linked bisindole alkaloid scalaridine A is described. An iridium catalyzed, directed C-H borylation of N-Boc-5-methoxyindole gave the corresponding 3-borylindole, which underwent a one-pot, double Suzuki-Miyaura cross-coupling reaction with 3,5-dibromopyridine to install the entire heteroaromatic framework of the natural product. Removal of the protecting groups gave a synthetic sample of scalaridine A, which was spectroscopically identical to that described in the isolation report.
