A concise asymmetric synthesis of (R)-2-chloro-5-(2-azetidinylmethoxy)pyridine (ABT-594) is presented in which the key intermediate t-butoxycarbonyl protected (2R)-azetidinylalcohol is obtained in three steps from the dibenzyl ester of D-aspartic acid in 44% yield and >99% ee.
提出了一种简明的不对称合成(R)-2-氯-5-(2-氮杂环丁烷基甲氧基)吡啶(ABT-594)的方法,其中关键的中间体叔丁氧羰基保护的(2 R)-氮杂环丁烷基醇可通过以下三个步骤获得D-天冬氨酸的二苄基酯,收率44%,ee> 99%。
