The preparation of optically active 1-amino-2-(hydroxymethyl)cyclopropanecarboxylic acid has been achieved by a route involving cycloalkylation of dimethyl malonate with epichlorohydrin and subsequent Hofmann rearrangement. The reaction of epichlorohydrin with nucleophiles may occur al either electrophilic site, epoxide or halide. Based on the absolute configuration of the starting materials and the
光学活性的1-氨基-2-(羟甲基)环丙烷羧酸的制备已经通过一种途径进行,该途径包括将丙二酸二甲酯与表氯醇环烷基化并随后进行霍夫曼重排。表氯醇与亲核试剂的反应可能发生在亲电部位,环氧化物或卤化物上。基于起始原料和获得的内酯的绝对构型,已表明环烷基化的起始步骤发生在环氧化物部分。1-氨基-2-(羟甲基)-环丙烷甲酸是植物生长激素乙烯前体的类似物,将用于亲和纯化技术和抗体的产生中。
