合成路线 1(1. 合成:3163-27-7)
产率:99%
合成条件:With ethyl 2,2-dibromoacetoacetate; triphenylphosphine In dichloromethane at 20℃; for 0.50 h;
实验步骤:通用方法:在环境温度下,将α,α-二乙酰乙酸乙酯2a(0.41mmol,1.2当量),醇1a-1s(0.34mmol,1.0当量)和Ph3P(0.68mmol,2.0当量)加入空气中的3mL DCE中。 在室温下搅拌适当的时间(通过TLC监测)后,通过加入H 2 O(3mL)淬灭反应,然后用乙酸乙酯(3×3mL)萃取。 将合并的有机层用盐水洗涤,用Na 2 SO 4干燥并浓缩。 通过硅胶柱色谱法纯化粗产物,用石油醚或石油醚和乙酸乙酯的混合物作为洗脱剂,得到相应的产物3a-3s。
