cyclohexanes in total regio‐, diastereo‐ and enantioselective fashion. The presence of nitro, hydroxy and keto groups in the product provides a wide scope for further structural transformations. Furthermore, the utility of the catalytic process is demonstrated in the context of enantioselective formal synthesis of ABT‐341, a DPP4 inhibitor.
对映选择性串联迈克尔-羟醛和氧化迈克尔-羟醛方法已经实现了以区域,非对映和对映选择性的方式形成各种取代的环己烷。产品中硝基,羟基和酮基的存在为进一步的结构转化提供了广阔的空间。此外,在DPP4抑制剂ABT-341的对映选择性形式合成中证明了催化过程的实用性。
