Ioannidou, Heraklidia A. published the artcileThree-Step Synthesis of Ethyl Canthinone-1-carboxylates from Ethyl 4-Bromo-6-methoxy-1,5-naphthyridine-3-carboxylate via a Pd-Catalyzed Suzuki-Miyaura Coupling and a Cu-Catalyzed Amidation Reaction, COA of Formula: C7H8BClO2, the publication is Journal of Organic Chemistry (2011), 76(12), 5113-5122, database is CAplus and MEDLINE.
Et canthin-6-one-1-carboxylate (I) and nine analogs were prepared from readily prepared Et 4-bromo-6-methoxy-1,5-naphthyridine-3-carboxylate via a three-step non-classical approach that focused on construction of the central pyrrole (ring B) using Pd-catalyzed Suzuki-Miyaura coupling followed by Cu-catalyzed C-N coupling. Furthermore, treatment of I with NaOH in DCM/MeOH (9:1) gave the canthin-6-one-1-carboxylic acid in high yield. All compounds are fully characterized.
