A Domino Amidation Route to Indolines and Indoles: Rapid Syntheses of Anhydrolycorinone, Hippadine, Oxoassoanine, and Pratosine
摘要:
When subjected to palladium-catalyzed amidation conditions, 2-triflyloxy phenethyl carbonates undergo, in addition to the expected aryl cross-coupling, an additional amidation with net displacement of the carbonate. The result is a one-step synthesis of indolines which may be oxidized to indoles. The utility of the procedure is illustrated by the two- or three-step syntheses of anhydrolycorinone, hippadine, oxoassoanine, and pratosine.
