10-tetraaryl-tetracyclo[6.2.1.0.03,6]undeca-2,4,6,9-tetraene (3), was prepared by cycloaddition of dichlorocarbene to the benzene nucleus of 2,7-di-tert-butyl-4,5,9,10-tetraaryl-tricyclo[6.2.0.03,6]deca-1,3(6),4,7,9-pentaene (1). On Ag+-induced methanolysis and acetolysis of 3a, its endo-Cl reacted easily and endo-methoxy (6) and endo-acetoxy derivative (9) were obtained, respectively, probably via bishomoallyl
