visible-light-enabled catalytic formylation of fluoroalkyl imines is developed. With readily accessible starting materials and organocatalysts, this method provides a general approach to masked fluoroalkyl amino aldehydes. A synergistic catalytic effect between the photosensitizer and the H atom transfer agent was proven pivotal to this transformation. After removing the mask, free aldehydes can be obtained and
开发了可见光使氟代烷基亚胺催化甲酰化。利用容易获得的起始原料和有机催化剂,该方法提供了掩蔽的氟代烷基氨基醛的一般方法。光敏剂和氢原子转移剂之间的协同催化作用被证明对这种转化至关重要。除去掩膜后,可以获得游离醛并将其进一步转化为各种β-氟烷基β-氨基醇,它们是生物活性和药物化合物合成中的有吸引力的构建基块。
