Dielectrically controlled resolution (DCR) of 3-aminopiperidine via diastereomeric salt formation with N-tosyl-(S)-phenylalanine
摘要:
A useful key intermediate for the dipeptidyl peptidase-4 (DPP-4) inhibitor, 3-aminopiperidine 1, was successfully resolved with an enantiomerically pure resolving agent, N-tosyl-(S)-phenylalanine 2, to give both stereoisomers (R)-1 and (S)-1 as a less-soluble diastereomeric salt with (S)-2, via a dielectrically controlled resolution (OCR) phenomenon.

One-pot synthesis of cyclohexylamine and <i>N</i>-aryl pyrroles <i>via</i> hydrogenation of nitroarenes over the Pd<sub>0.5</sub>Ru<sub>0.5</sub>-PVP catalyst
The direct synthesis of cyclohexylamine via the hydrogenation of nitrobenzene over monometallic (Pd, Ru or Rh) and bimetallic (PdxRu1−x) catalysts was studied. The Pd0.5Ru0.5-PVP catalyst was the most effective catalyst for this reaction. The catalyst can be reused and applied for the synthesis of N-aryl pyrroles and quinoxalines from nitrobenzenes.
研究了在单金属(Pd,Ru或Rh)和双金属(Pd x Ru 1- x)催化剂上通过硝基苯加氢直接合成环己胺的方法。Pd 0.5 Ru 0.5 -PVP催化剂是该反应最有效的催化剂。该催化剂可以重复使用并用于由硝基苯合成N-芳基吡咯和喹喔啉。
