ruthenium-catalyzed direct asymmetric reductive amination of an α-alkoxy ketone, a structural motif for which it is more challenging to implement such a transformation than 1,3-dicarbonyl compounds. The discovery of a novel ruthenium catalyst that was highly stable to air and moisture, as well as being readily prepared from commercially available reagents, enabled rapid access to a key synthetic chiral primary amine
在这里,我们报告了一种新型、高效的钌催化的 α-烷氧基酮的直接不对称还原胺化,这是一种结构基序,实现这种转化比 1,3-二羰基化合物更具挑战性。一种对空气和湿气高度稳定的新型钌催化剂的发现,以及易于从市售试剂中制备的新型钌催化剂的发现,使人们能够快速获得关键的合成手性伯胺,从而获得 TAK-915,TAK-915 是一种药物活性成分PDE2A抑制剂。
