The first highly enantioselective conjugate addition of 2-acetyl azaarenes to α-substituted-β-nitroacrylates was successfully realized under mild conditions by a Ni(II)-bisoxazoline complex, providing the desired adducts bearing an all-carbon quaternary stereocenter in high yield with excellent enantioselectivity. The products obtained in this system could be readily converted into optically active β2,2-amino esters, succinates, lactones, and lactams. In the experiment, the researchers used many compounds, for example, 1-(1-Methyl-1H-imidazol-2-yl)ethanone (cas: 85692-37-1Safety of 1-(1-Methyl-1H-imidazol-2-yl)ethanone).
1-(1-Methyl-1H-imidazol-2-yl)ethanone (cas: 85692-37-1) belongs to imidazole derivatives. 1H-imidazole is an imidazole tautomer which has the migrating hydrogen at position 1. It is a conjugate base of an imidazolium cation. It is a conjugate acid of an imidazolide. It is a tautomer of a 4H-imidazole. This ring system is present in important biological building blocks, such as histidine and the related hormone histamine.Safety of 1-(1-Methyl-1H-imidazol-2-yl)ethanone
