Chen, Li-Yuan published the artcileRegiodivergent Synthesis of Methylene and Methyl Ring-Fused Isoquinolinones: Base-Promoted Isomerization of N-Allyl Amides, Application In Synthesis of 74317-85-4, the main research area is methylene methyl tricyclic isoquinolinone preparation regioselective; alkenyl bromobenzamide aza Wacker Heck reaction palladium.
Methylene and Me tricyclic isoquinolinones were selectively prepared using a palladium(II)-catalyzed aerobic aza-Wacker reaction, followed by a base- and temperature-controlled Heck reaction catalyzed by palladium(0). Exo- to endo-double-bond migration in isoquinolinones was achieved with 93-99% yields by treatment of the Heck products with Cs2CO3 in DMSO (DMSO) at 150°C. A probable mechanism for Cs2CO3-promoted olefin isomerization was proposed and examined using D-isotope labeling experiments Finally, yuanamide, a 13-methyl-8-oxoprotoberberine alkaloid, was synthesized using the palladium-catalyzed aza-Wacker/Heck/migration sequence.
