    • A method of preparing 1-phenyl-1-diethylaminocarbonyl-2-phthalimidomethyl-cyclopropane-Z and key intermediates therefor are disclosed.This method is characterized by the following successive steps:opening of the 1-phenyl-2-oxo-3-oxa-bicyclo(3:1:0)-hexane by diethylamine or a tertiary amine with the aid of a Lewis acid/amine complex:the 1-phenyl-1-diethylaminocarbonyl-2-hydroxymethyl-cyclopropane-Z thus obtained is converted into a 2-chlorinated derivative by the action of a chlorination reagent such as thionyl chloride; andthe 1-phenyl-1-diethylaminocarbonyl-2-chloromethylcyclopropane-Z is reacted with a phthalimide salt in an organic solvent to produce the 1-phenyl-1-diethylaminocarbonyl-2-phthaliumidomethyl-cyclopropane-Z.
    • 公开了制备1-苯基-1-二乙基氨基羰基-2-邻苯二甲酰亚氨基甲基 - 环丙烷-Z的方法及其关键中间体。 该方法的特征在于以下连续步骤:借助路易斯酸/胺,通过二乙胺或叔胺打开1-苯基-2-氧代-3-氧杂双环(3:1:0) - 己烷 络合物:将由此获得的1-苯基-1-二乙基氨基羰基-2-羟甲基 - 环丙烷-Z通过氯化试剂如亚硫酰氯的作用转化为2-氯代衍生物; 并将1-苯基-1-二乙基氨基羰基-2-氯甲基环丙烷-Z与邻苯二甲酰亚胺盐在有机溶剂中反应,生成1-苯基-1-二乙基氨基羰基-2-邻苯二甲酰基甲基 - 环丙烷-Z。
