the hemiaminal with a cyanide source, allows for the straightforward synthesis of α‐amino nitriles. The methodology presented here, displays high levels of chemoselectivity allowing for the reduction of amides in the presence of functional groups such as ketones, imines, aldehydes, and acids, which affords a simple route for the synthesis of α‐amino nitriles with a broad scope of functionalities in high
Mo(CO)6催化将酰胺选择性还原成中间体半胱氨酸再加上廉价且易于操作的TMDS(1,1,3,3-四甲基二硅氧烷)作为还原剂,随后用氰化物源捕获半胱氨酸,可以直接合成α-氨基腈。此处介绍的方法显示出高水平的化学选择性,可以在存在官能团(例如酮,亚胺,醛和酸)的情况下还原酰胺,这为广泛范围内的α-氨基腈的合成提供了一条简单途径高产量的功能。此外,该方法的适用性通过扩大规模的实验以及将目标化合物衍生为可合成的有趣产品来证明。
