Furo[3,2-b]benzofuran was demonstrated to be an intermediate for the synthesis of dibenzofuran and 1,4-epoxy-1,4-dihydrodibenzofuran ring systems. Starting from the readily available aryl 3-bromomethyl-2-benzo[b]furyl ketones, a method was developed for the synthesis of 4-arylbenzofuro[2,3-d]pyridazines.
