Here, an enantioselective nickel-hydride catalyzed hydroalkylation of readily accessible β-alkyl-α,β-unsaturated amides to form structurally diverse β-chiral amides e.g., I was reported. This process was proposed to proceed through an enantiodifferentiating syn-hydrometalation of nickel hydride, forming chiral alkylnickel at β-position in which regioselectivity is different than that with copper hydride. This regio-reversed hydronickellation process provided a complementary approach to access enantioenriched β-functionalization amides with a stereocenter at β-position. In the experiment, the researchers used many compounds, for example, 4-Methoxy-2-methylpyridine (cas: 24103-75-1SDS of cas: 24103-75-1).
4-Methoxy-2-methylpyridine (cas: 24103-75-1) belongs to pyridine derivatives. Pyridine has a conjugated system of six π electrons that are delocalized over the ring. The molecule is planar and, thus, follows the Hückel criteria for aromatic systems. Pyridine, its benzo and pyridine-based compounds play diverse roles in organic chemistry. Pyridine-based materials are valued for their optical and physical properties as well as their medical potential. SDS of cas: 24103-75-1
