A regio- and stereoselective method has been developed for the synthesis of novel fluorinated 2-aminocyclohexanecarboxylic acid derivatives with the fluorine attached to position 4 of the ring. The synthesis starts from either cis- or trans-β-aminocyclohex-4-enecarboxylic acids and involves regio- and stereoselective transformation of the ring C-C double bond through iodooxazine formation and hydroxylation, followed by hydroxy-fluorine or oxo-fluorine exchange.
已开发出一种区域和立体选择性方法,用于合成新型氟化 2-氨基环己烷羧酸衍生物,其中氟原子连接在环的 4 位。合成从顺式或反式-β-氨基环己-4-烯羧酸开始,通过碘噁嗪形成和羟化,然后通过羟基-氟或羰基-氟交换,实现环 C-C 双键的区域和立体选择性转化。
