Deuterated unsaturated fragments have gained increasing attention because of their roles in understanding reaction mechanisms and pharmaceutical potentials. Due to the difficulties of the existing synthetic methods, it is highly desirable to develop an effective, highly site selective, and environmentally friendly method to introduce deuterium into unsaturated fragments. Herein, we describe a biocatalytic
氘代不饱和片段因其在理解反应机制和药物潜力方面的作用而受到越来越多的关注。由于现有合成方法的困难,非常希望开发一种有效的、高位点选择性和环境友好的方法将氘引入不饱和片段中。在此,我们描述了一种生物催化氢同位素交换 (HIE) 反应,由来自黑曲霉( An Fdc)的工程化阿魏酸脱羧酶催化不饱和片段形成 C(sp 2 )-D 键,该酶自然催化肉桂酸的可逆转化为苯乙烯和CO 2。一个Fdc 显示出有希望的合成潜力和广泛的底物相容性,提供了一系列具有高产率、位点选择性和 D 掺入的氘代芳族杂环和苯乙烯衍生物。
