A direct oxidative radical decarboxylative cyanomethylation of carboxylic acids is described using 3-azido-2-methylbut-3-en-2-ol as the carbon-centered radical acceptor. The transformation is applicable to structurally diverse α-amino acids, α-oxy acids, α-keto acids, pentofuranuronic acids, and hexopyranuronic acids. The mechanistic investigations suggest that a radical process is involved in the
使用 3-azido-2-methylbut-3-en-2-ol 作为以碳为中心的自由基受体,描述了羧酸的直接氧化自由基脱羧氰甲基化。该转化适用于结构多样的α-氨基酸、α-含氧酸、α-酮酸、戊呋喃糖醛酸和己吡喃糖醛酸。机械研究表明,转变涉及一个激进的过程。这项工作为构建具有生物学相关性的β-氨基酸、5-脱氧-己呋喃糖和 6-脱氧-庚糖提供了一种潜在的方法。
