  Synthesis of PAF antagonist MK-287

  摘要：

  The synthesis of PAF antagonist MK-287 is described. Our route utilizes a 5-aryl-substituted butyrolactone as the key optically active intermediate, which is constructed in four steps from commercially available 5-iodovanillin. Asymmetry is introduced using beta-chlorodiisopinocampheylborane to reduce a prochiral ketone. The second asymmetric center is installed relative to the existing stereocenter with stereocontrol exceeding 50:1. This step utilizes a copper-catalyzed Grignard displacement of an alpha-bromo ether. The alpha-bromo ether was generated using trimethylsilyl bromide activation of a silylated hemiacetal. The details leading to our development of the silyl acetal method for anomeric activation are also described.
