HIGHLY REGIOSELECTIVE INTRAMOLECULAR BIARYL COUPLING REACTION OF A PHENYL BENZOATE DERIVATIVE FOR THE SYNTHESIS OF GRAPHISLACTONE G
[摘要]:The 6H-dibenzo[b,d]pyran-6-one type natural product graphislactone G was synthesized using a palladium-mediated aryl-aryl coupling reaction of the phenyl benzoate derivative. The regioselectivity in the coupling step was also investigated.
