  通过β-内酰胺开口合成新型三环BACE1抑制剂战斗部的简单方法

  摘要：

  已经从通过施陶丁格反应获得的β-内酰胺前体中阐述了一种合成潜在的β-分泌酶1（BACE-1）抑制剂的新方法。在连续还原/ Mitsunobu醚化反应后，β-内酰胺的开环可进入关键的中间体三取代四氢呋喃。该策略允许通过β-内酰胺的差向异构化来部分控制立体化学。最后，通过引入酰胺连接基进一步修饰am，以递送假定的BACE-1抑制剂。

  The dual activation of α-keto esters and formaldehyde tert-butyl hydrazone by BINAM-derived bis-ureas is the key to achieve high reactivity and excellent enantioselectivities in nucleophilic addition (formal carbonyl-ene reaction) to functionalized tertiary carbinols. Ensuing high-yielding diazene-to-aldehyde tranformations and subsequent derivatizations provides a direct entry to a variety of densely
