摘 要:以1-氯-2-丁酮、3-(2,2,2-三氟乙氧基)丙烯醛及氨水为原料、过一硫酸氢钾(Oxone)作氧化剂、十二烷基硫酸钠(SDS)作相转移催化剂,经缩合、取代、氧化3步反应合成兰索拉唑收率16.3%。分别考察反应时间、反应体系和氧化剂等因素对收率的影响。通过1H NMR与MS确证了兰索拉唑的结构。该工艺流程短,适于工业化生产。

Abstract:Lansoprazole was synthesized from 1-chloro-2-butanone,3-(2,2,2-trifluoroethoxyl)-acraldehyde and ammonium hydroxide via condensation, substitution and oxidation. Oxone and SDS were used as the oxidant and the phase transfer catalyst respectively. Reaction conditions were investigated and improved. The structure of the final product was confirmed by 1H NMR and MS. This improved process reduced the reaction steps, and was suitable for industrial manufacturing.
Key words:proton pump inhibitors;lansoprazole;synthesis
