摘要
报道以氯乙酸氯为起始原料,依次合成氯乙酸叔丁酯(Ⅱ)、三苯基膦烯乙酸叔丁酯(Ⅱ)、3-(2-甲酰基苯基-2(E)-丙烯酸叔丁酯(Ⅳ),(Ⅳ)与3-氨基丁烯酸乙酯环合得到拉西地平(Ⅰ)的工艺过程。
The synthetic route with chloroacetyl chloride gave tert-butyl chloroacetate (Ⅱ), triphenylphosphine (Ⅲ) and tart-butyl 3-(2-formylphenyl)-2 (E)-propenoate (Ⅳ), then Ⅳ was cyclized with ethyl 3-aminocrotonate in acetic acid and lacidipine (Ⅰ) was prepared.
