We wish to record a synthesis of novel [8](2,5)heterophanes starting from 1,4oyolododeoanedione (I) which is readily accessible from oyolododecanone (1). Dehydration of the diketone I by treating with a mixture of phosphorus pentoxide and ethanol (2) at 80' for 1 hr gave [8](2,5)furanophane (II), b.
