  Synthesis and structure–activity relationship studies of 1,3-disubstituted 2-propanols as BACE-1 inhibitors

  摘要：

  A library of 1,3-disubstituted 2-propanols was synthesized and evaluated as low molecular weight probes for beta-secretase inhibition. By screening a library of 121 1,3-disubstituted 2-propanol derivatives, we identified few compounds inhibiting the enzyme at low micromolar concentrations. The initial hits were optimized to yield a potent BACE-1 inhibitor exhibiting an IC50 constant in the nanomolar range. Exploration of the pharmacological properties revealed that these small molecular inhibitors possessed a high selectivity over cathepsin D and desirable physicochemical properties beneficial to cross the blood-brain barrier.

  branched allylic carbon-heteroatom bonds from racemic, secondary allylic trichloroacetimidates has been developed. The branched allylic substrates undergo dynamic kinetic asymmetric substitution reactions with a number of unactivated anilines and carboxylic acids as well as unactivated aromatic thiols in the presence of a chiral bicyclo[3.3.0]octadiene-ligated iridium catalyst. The allylic C−O, C−N

  已经开发了一种广泛适用的方法，用于从外消旋、仲烯丙基三氯乙酰亚胺酯中区域和对映选择性构建支链烯丙基碳-杂原子键。在手性双环[3.3.0]辛二烯-连接的铱催化剂存在下，支化烯丙基底物与许多未活化的苯胺和羧酸以及未活化的芳族硫醇发生动态动力学不对称取代反应。以合成有用的产率和选择性获得含有烯丙基 C-O、C-N 和 C-S 键的产物。机理研究表明，铱催化的杂原子亲核试剂与烯丙基三氯乙酰亚胺酯底物通过外球亲核加成机制进行对映选择性取代反应。此外，手性二烯连接的铱催化剂可有效促进无环仲苯胺的不对称胺化。重要的是，这种催化铱方法能够使用烷基取代的烯丙基亲电试剂。

  trichloroacetimidates possessing β-nitrogen substituents and proximal nitrogen-containing heterocycles, via chiral diene-ligated rhodium-catalyzed dynamic kinetic asymmetric transformations (DYKAT), provides branched allylic 1,2-diamines with high enantioselectivity. The catalytic system can be applied to the synthesis of 1,2-diamines possessing two contiguous stereocenters with excellent diastereoselectivity

  通过手性二烯连接的铑催化的动态动力学不对称转化（DYKAT），具有β-氮取代基和近端含氮杂环的外消旋仲和叔烯丙基三氯乙二酰亚胺的胺化反应提供了高对映选择性的支链烯丙基1,2-二胺。该催化体系可用于合成具有两个非对映选择性的，具有两个连续立体中心的1,2-二胺。此外，含氮杂环抑制竞争性乙烯基叠氮基的形成，从而允许具有叔和季中心的1,2-二胺的高对映选择性合成。
