preparation of diverse, enantioenriched α-deuterated α-amino acids. Distinct from the well-established two-electron transformations, this radical-based strategy offers the unrivaled capacity of the convergent unification of readily accessible feedstock carboxylic acids and a chiral methyleneoxazolidinone fragment and the simultaneous highly diastereo-, chemo-, and regioselective incorporation of deuterium
已经开发出一种温和的,通用的有机光氧化还原方案,用于制备多种对映体富集的α-氘代α-氨基酸。与公认的双电子转化不同,这种基于自由基的策略提供了无与伦比的能力,可轻松获得的原料羧酸和手性亚甲基恶唑烷酮片段的融合统一,以及氘的高度非对映,化学和区域选择性同时引入。此外,该方法解决了将空间需求侧链安装到α-氨基酸中的长期挑战。
