(MFA). A roundabout strategy was put forward based on MFHP to overcome the shortcomings of MFA to extend its storage life and reduce its cost of shipment and storage. In our work, a novel and facile method for the synthesis of MFHP was developed based on Claisen salts and formaldehyde in water as followed: 37% formaldehyde aqueous (9.0 equiv.) was dropped into the aqueous of Claisen salt (1.0 equiv.)
摘要 2-氟-3-羟基丙酸甲酯 (MFHP) 及其衍生物 3-氯-2-氟丙酸甲酯 (MCFP) 很容易转化为 2-氟丙烯酸甲酯 (MFA)。提出基于MFHP的迂回策略,克服MFA的缺点,延长其存储寿命,降低其运输和存储成本。在我们的工作中,基于克莱森盐和甲醛在水中开发了一种新颖简便的 MFHP 合成方法,如下所示:将 37% 甲醛水溶液(9.0 当量)滴入克莱森盐(1.0 当量)水溶液中,然后NaHCO 3 (1.0当量)室温反应2-3 h得到MFHP,收率为81.3%。
