Photocyclization of the substituted 2-(naphth-1-yl)-3-(thien-2-yl)propenoic acid (3) in the presence of iodine and air in a benzene-cyclohexane mixture afforded a separable mixture of three compounds, phenanthro[2,1-b]thiophene-10-carboxylic acid (4), phenanthro[2,1-b]thiothene (5), and naphtho[1,8-cde]-thieno[3,2-g][2]benzopyran (6)
在苯和环己烷混合物中,在碘和空气存在下,将取代的2-(萘-1-基)-3-(噻吩-2-基)丙酸(3)光环化,得到可分离的三种化合物菲并[2,1- b ]噻吩-10-甲酸(4),菲并[2,1- b ] thiothene(5),和萘并[1,8- CDE ] -噻吩并[3,2-克] [2苯并吡喃(6)
