formed stereocenter as well as site selectivity on both the heteroarene and the amide. This is achieved by the use of a chiral phosphoric acid catalyst in conjunction with diacetyl as a combined hydrogen atom transfer reagent and oxidant. Diacetyl is directly photoexcitable, and thus, no extraneous photocatalyst is required: an added feature that contributes to the simplicity and practicality of the

芳烃构建复杂性的最强大方法之一。最理想的变体涉及每个伙伴上 C-H 键的正式氧化偶联,从而得到最简单的起始材料。我们在此公开了一种方法,该方法能够实现线性酰胺和杂
芳烃的这种偶联,并完全控制新形成的立构中心处的对映选择性以及杂
芳烃和酰胺两者上的位点选择性。这是通过使用手性
磷酸催化剂与联乙酰作为组合的氢原子转移试剂和氧化剂来实现的。
二乙酰可直接光激发,因此不需要额外的光催化剂:这一附加功能有助于该方案的简单性和实用性。
