Intramolecular double or triple Suzuki coupling reaction of substituted di-or tribromobenzenes. An easy synthesis of fused tri-or tetracycles with a benzene core
Double or triple intramolecular Suzuki coupling reaction has been developed for the efficient synthesis of tri-or tetracyclic products with a benzene core in good yields. The reaction was realized via a one-pot procedure combining the hydroboration of the CC bond in the starting aryl halides and the intramolecular Suzuki coupling.
