SYNTHESIS OF BENZOFUROBENZOFURAN AND BENZOFUROBENZOFURAN

A convenient method was developed for the synthesis of benzofurobenzofuran and benzofurobenzofuran by the structurally directed heterocyclization of hydrosalicyloin to 4b,9b-dihydrobenzofurobenzofuran or 5a,10b-dihydrobenzofurobenzofuran and their subsequent homolytic bromination and dehydrobromination in the presence of a base.The stuctures of the cyclization products are determined by the nature of the dehydrating agent.The possible mechanism of the cyclization of hydrosalicyloin in the presence of acids is disscused.
