Gollner, Andreas published the artcileTwo-Step Total Syntheses of Canthin-6-one Alkaloids: New One-Pot Sequential Pd-Catalyzed Suzuki-Miyaura Coupling and Cu-Catalyzed Amidation Reaction, SDS of cas: 145349-62-8, the publication is Organic Letters (2010), 12(6), 1352-1355, database is CAplus and MEDLINE.
Canthin-6-one (I; R1 = R2 = H) and nine analogs including the naturally occurring 9-methoxycanthin-6-one (I; R1 = OMe, R2 = H) and amaroridine (I; R1 = H, R2 = OMe) are prepared rapidly and in high yields via a convergent “non-classical” strategy that focuses on construction of the central ring B. The strategy relies on concomitant Pd-catalyzed Suzuki-Miyaura C-C coupling followed by a Cu-catalyzed C-N coupling that can be achieved either stepwise or in a new one-pot protocol starting from the appropriate 8-bromo-1,5-naphthyridine.
