✦ Synopsis

previous papers, we reported the synthesis and diatropicity of 1,8-didehydro[14]annulenes annelated with naphthalene (1,2) or bensene (3). It seemed of considerable interest to prepare l, lO-didehydro[18]annulene fused with bensenoid system to compare the ring current in the 18n-electron system with that
