(E)-3-(Dimethylamino)-1-(2-hydroxyphenyl)prop-2-en-1-ones (2) were synthesized by the condensation reaction of o-hydroxyacetophenones (1) and N,N-dimethylformamide-dimethyl acetal (DMF-DMA). Using DMF as solvent and K2CO3 as base, 4'-phenyl-(1,1':2',1''-terphenyl)-2,3'-diol (3) were synthesized via the condensation reaction of intermediate 2 and 1,3-diphenylacetones. 3 were dissolved in the solution of acetonitrile-1% HCl (V:V=1:1) and irradiated by 500 W mercury lamp, and 1-hydroxy-2-phenyltriphenylenes were obtained. This process to synthesize 4 has the advantages of simple operation, high efficiency of the atomic, without oxidant and catalyst. Compounds 3 and 4 were confirmed by the method of FT-IR, 1H NMR, 13C NMR, HRMS.

Key words: 4'-phenyl-(1,1':2',1''-terphenyl)-2,3'-diol, 1-hydroxy-2-phenyltriphenylene, photocyclization reaction, condensation reaction
