合成路线 1（1. 合成：447-43-8）
产率：65%
合成条件：for 48 h; Reflux
实验步骤：通用方法：将底物（0.6mmol），溴乙烯2a（0.06mmol）的DMSO（1.1mL）混合物在敞口烧瓶中加热（油浴温度，反应时间在refPreviewPlaceHolderTable 2中规定）。 在反应完成后（通过TLC检查），将反应混合物用水（11mL）稀释，用NaCl饱和并用乙酸乙酯（5.x.4mL）萃取。 仅在合成芳基乙二醛的情况下，有机层另外用Na 2 CO 3（0.12mmol，在2mL水中），用饱和NaCl水溶液洗涤，并用无水Na 2 SO 4干燥。 萃取物的柱色谱（洗脱液：梯度石油醚/乙酸乙酯）得到纯产物。
