A short and concise synthesis of novel, chiral bicyclo[3.1.0]hex‐2‐ene amino acid derivatives 13 and 14 has been developed. The key step is a stereo‐ and regioselective allylic amination of exo‐ and endo‐methyl bicyclo[3.1.0]hex‐2‐ene‐6‐carboxylates 8 and 9, which were prepared from 7,7‐dichlorobicyclo[3.2.0]hept‐2‐en‐6‐one (1). These amino acid derivatives are useful building blocks in medicinal chemistry
已开发出一种简短的新型新颖手性双环[3.1.0]己-2-烯氨基酸衍生物13和14的合成方法。关键步骤是由7,7-二氯双环[3.2.0 ]制备的exo-和内甲基双环[3.1.0]己-2-烯-6-羧酸盐8和9的立体和区域选择性烯丙基胺化。] hept-2-en-6-one(1)。这些氨基酸衍生物在药物化学中是有用的组成部分,并且可以通过使用(+)- 1或(-)- 1作为起始原料制备为手性化合物。
