4-(2-呋喃基)-3-丁烯-2-酮合成路线

4-(2-呋喃基)-3-丁烯-2-酮制备

1.制法：

于装有搅拌器、温度计的反应瓶中，加入新蒸馏过渡糠醛（2）77g（0.75mol），600mL水，125mL丙酮，搅拌下冰水浴冷却至10℃，加入15mL（33%）的氢氧化钠水溶液，反应放热。室温搅拌反应4h。用10%的稀硫酸调至弱酸性。静置分层。水层常压蒸馏，直至馏出物澄清。分出油层，与上面的油层合并。将油层物减压蒸馏，收集114～118℃/1.33kPa或135～145℃/6.65kPa的馏分，得4-（2-呋喃基）-3-丁烯-2-酮（1）60～65g，冷后固化为黄色固体，mp37～39℃，收率60%。
