A simple and efficient procedure for the multigram synthesis of both (±)-trans- and (±)-cis-1-amino-2-(trifluoromethyl)cyclopropane-1-carboxylic acid was developed. The key step of the synthesis is the addition of 1-diazo-2,2,2-trifluoroethane to methyl 2-[(tert-butoxycarbonyl)amino]acrylate, followed by thermal decomposition of the resulting pyrazoline. Gram quantities of trans- and cis-1-amino-2
开发了一种简单有效的方法,可以合成(±)-反式和(±)-顺式-1-氨基-2-(三氟甲基)环丙烷-1-羧酸。合成的关键步骤是将1-重氮-2,2,2-三氟乙烷添加到2-[(叔丁氧基羰基)氨基]丙烯酸甲酯中,然后热分解吡唑啉。的克量的反式-和顺式-1-氨基-2-(三氟甲基)环丙烷-1-羧酸很容易从制备升-丝氨酸在一种合成运行。 氟-烯烃-氨基酸-催化剂-重氮化合物
