Abstract: A convergent and efficient synthesis of highly-oxygenated, angularly-fused polycyclic aromatic compounds has been developed. Nucleophilic addition of [4-(tri-n- butylstannyl) phenyl] lithium to a 3, 4-disubstituted-cyclobutene-1, 2-dione followed by appropriate protection of the hydroxyl group and thermal rearrangement of the 0-protected addition product generated a 1, 4-dioxygenated-2, 3-disubstituted-6-(tri-n-butylst~ yl) ...
