nitriles to yield primary amines and also valuable α,α-dideutero analogues. Raney nickel proved to be a useful catalyst for the transformation of a wide range of nitriles under reasonably mild conditions with excellent deuterium incorporation (>90 %) and quantitative conversion. Among known model compounds, three new deuterated primary amines were prepared. The large-scale synthesis of deuterated tryptamine
已经开发了一种简单有效的连续流方法,用于腈的氢化和还原氘化反应,以生成伯胺以及有价值的α,α-二氘代类似物。阮内镍被证明是在合理的温和条件下以优异的氘掺入率(> 90%)和定量转化率,可用于多种腈转化的有用催化剂。在已知的模型化合物中,制备了三种新的氘代伯胺。还进行了氘代色胺的大规模合成以在流动条件下递送1.1g产物。
