A convenient route to 1-aminocyclopropane-1-carboxylic acid (1, ACC) and N-protected derivatives was developed. This route utilizes a bisalkylation of an O-benzyl glycine derived imine followed by global deprotection via hydrogenation. Direct isolation of ACC from a non-aqueous stream or efficient conversion to N-protected derivatives in a single flask is described.
开发了一条方便的路线来合成1-氨基环丙酸(1,ACC)及其N保护衍生物。该路线利用了O-苄基甘氨酸衍生的亚胺的双烷基化反应,随后进行整体去保护反应,通过加氢处理。描述了从非水相流中直接分离ACC或在单个反应瓶中高效转化为N保护衍生物的方法。
