conversion and excellent enantioselectivity and shows a wide substrate scope. The reduced products are valuable chiral synthons characterized by two vicinal nitrogen‐containing functional groups that can be further modified by functional group inter‐conversion thanks to the synthetic versatility of the nitro moiety. The chemo‐enzymatic synthesis of (R)‐N,N′‐(1‐phenylethane‐1,2‐diyl)diacetamide from
首次描述了烯还原酶催化的(Z)-β-酰基氨基硝基烯烃的还原。该反应以高转化率和优异的对映选择性发生,并显示出较宽的底物范围。还原产物是有价值的手性合成子,其特征在于两个邻位含氮官能团,由于硝基部分具有合成多功能性,可以通过官能团相互转化进一步修饰。由易获得的(Z)-N-(2-硝基-1-苯基乙烯基)乙酰胺化学合成酶(R)-N,N' -(1-苯基乙烷-1,2-二基)二乙酰胺的方法为该合成程序的代表性应用。
