C3 symmetric triformylsumanene was selectively synthesized from C3 symmetric syn-tris(oxonorborneno)benzene, featuring ring-opening/closing metathesis reactions of syn-tris(methoxymethylnorbornadieno)benzene and DDQ oxidation. Triformylsumanene can be an intermediate to synthesize C3 symmetric trisubstituted sumanenes by further transformation. Tris(ethoxycarbonylethenyl)sumanene was prepared through the Horner–Wadsworth–Emmons reaction. Its optical and electrochemical behaviors were investigated.
