The condensation of naphthalene-1,2-dicarboxylicanhydride with 2-naphthylaceticacid gave the two structurally isomeric (2-naphthylmethylene)naphtho[1,2-c]furanones (VII) and (VIII) in the ratio 7 : 1. 2-[2-(2-Naphthyl)-ethyl]-1-naphthoic acid (IX), formed by reduction of the 3-substituted 1-ketone (VII) has been converted into 15H-cyclohepta[2,1-a:4,5-a′]dinaphthalen-15-one (IV).
萘-1,2-二羧酸酐与2-萘乙酸的缩合得到比例为7:1. 2的两个结构异构的(2-萘基亚甲基)萘[1,2- c ]呋喃酮(VII)和(VIII)。通过还原3-取代的1-酮(VII)形成的-[2-(2-萘基-乙基)-1-萘甲酸(IX)已转化为15 H-环庚[2,1- a: 4,5 - a ']二萘基-15-一(IV)。
