| 從圖5-4可以看出,化合物29m在δ 13.49左右沒有出現(xiàn)吸收峰,說(shuō)明羧基消失;在δ 9.08-7.00處出現(xiàn)的吸收峰歸屬于喹啉環(huán)和苯環(huán)9個(gè)氫質(zhì)子吸收峰;在δ 5.92-5.87處出現(xiàn)的吸收峰歸屬于吡喃環(huán)-CH上氫質(zhì)子吸收峰,在δ 3.79處出現(xiàn)一個(gè)較強(qiáng)的單峰,歸屬于-OCH3上3個(gè)氫質(zhì)子吸收峰;δ 3.45-3.35處出現(xiàn)的吸收峰,歸屬于吡喃環(huán)-CH2上2個(gè)氫質(zhì)子吸收峰。 |

| As shown in Fig.5-4 , compound 29m did not show absorption peak at about δ13.49 , this showed carboxyl group disappeared ; At δ9.08-7.00 the absorption peaks were attributed to absorption peaks which were from nine hydrogen proton on quinoline ring and benzene ring . At δ5.92-5.87 the absorption peaks were attributed to absorption peaks which were from hydrogen proton on -CH of pyrane ring , there was a comparely strong single peak at δ3.79 and it was attributed to absorption peaks of three hydrogen proton on -OCH3 , there was absorption peaks at δ 3.45-3.35 and it was attributed to absorption peaks of two hydrogen proton on –CH2 of pyrane ring . |
