The traditional Eschweiler–Clarke reaction is a three-component process involving formaldehyde, amine, and formic acid. In this work, we showed that the reductive potential of formaldehyde was sufficient to provide methylation of secondary amines in the absence of acidic additives. Various acid-sensitive moieties remain intact under developed conditions. The scalability of the elaborated approach was
传统的埃施韦勒-克拉克反应是一个三组分过程,涉及甲醛、胺和甲酸。在这项工作中,我们表明,在没有酸性添加剂的情况下,甲醛的还原电位足以提供仲胺的甲基化。各种酸敏感部分在发达条件下保持完整。多种产品都展示了精心设计的方法的可扩展性。抗真菌剂布替萘芬的合成证明了所开发方法的制备效用。
