【摘要】 利用香兰素作原料合成了中间体3-甲氧基-4-丁氧基苯甲醛和3-甲氧基-4-(α-乙酸)氧基苯甲醛,再进一步合成了四种新型的Schiff碱．反应是在乙醇水溶液中进行,反应体系的溶液pH值通常在 8～9之间．所合成的中间体和产物均进行UV、IR、1H NMR和13C NMR表征以及元素分析．更多还原

【Abstract】 This paper reported that the two intermediates and the new four Schiff bases synthesized. The two intermediates were prepared from vanillin and 1 -butylbromide or 2-chloroacetic acid respectively,and the two Schiff bases were synthesized from 3-methoxy-4-butoxybenzaldehyde and 2-amino-4-methylphenol or 2-aminophenylmethanol, the others were done from 3-methoxy-4-carboxymethylbenzaldehyde and aminoacetic acid or 2-amino-4-methylphenol respectively. The reacting condition was based on the solution of pH from 8 to 9, and the solvent was ethanol aqueous solution. The intermediates and products were characterized by element analysis , UV ,IR,1H NMR and 13C NMR.更多还原
