  摘要：

  描述了一种实用的不对称合成3,7-二氮杂双环[3.3.0]辛烷衍生物（1）的方法，该衍生物是一类新型的强效CCR5受体拮抗剂的代表。通过使用（R）-MeOBIPHEP作为配体，通过钌催化的不对称还原胺化作用引入1的苄胺立体异构中心。通过Parikh-Doering氧化制备的醛4在还原胺化反应中无需进行后处理，不仅简化了工艺，而且克服了4的不稳定性。通过[3 + 2]环加成获得3，7-二氮杂双环[3.3.0]辛烷核心。

  摘要：

  The unsymmetrical nicotinamide-N-oxide moiety in compound I was replaced with symmetrical isonicotinamides as well as 4,6-dimethyl pyrimidine-5-carboxamides. Compound 16 from the latter set reduced the number of rotamers, improved potency of inhibiting UIV entry, slightly diminished the affinity for the muscarine receptors and showed very good oral absorption.
