Total Syntheses of Riccardins A, B, and C, Cytotoxic Macrocyclic Bis(bibenzyls) from Liverworts

Di-O-methylriccardin A (3), riccardin A (1), and riccardin B (4) were synthesized by convergent schemes.Rings A and D of both riccardin A and B, as well as rings B and C of riccardin B were joined by the Ullmann ether synthesis.The aryl-aryl bond in ricca

THE SYNTHESIS OF RICCARDIN C

The macrocyclic bis(bibenzyl) riccardin C, isolated from Riccardia multifida was synthesized in an unambiguous way by Ni(O) assisted intramolecular aryl-aryl bond formation from a diiodobenzoate as the key step.
