The palladium(0) Suzuki cross-coupling reaction as the key step in the synthesis of aporphinoids
Abstract We report a flexible approach to the total synthesis of 4,5-dioxoaporphines based on the palladium(0) catalyzed Suzuki cross-coupling of phenylboronic acids with sterically hindered 2-bromo… Expand
