Reported herein is a conceptually novel organocatalytic strategy for the formylation of boronic acids. New reactivity is engineered into the α‐amino‐acid‐forming Petasis reaction occurring between aryl boronic acids, amines, and glyoxylic acids to prepare aldehydes. The operational simplicity of the process and its ability to generate structurally diverse and valued aryl, heteroaryl, and α,β‐unsaturated
本文报道了用于硼酸甲酰化的概念上新颖的有机催化策略。在芳基硼酸,胺和乙醛酸之间发生的α-氨基酸形成Petasis反应中引入了新的反应性,以制备醛。该方法的操作简便性及其生成结构多样且有价值的包含多种官能团的芳基,杂芳基和α,β-不饱和醛的能力证明了这种新合成策略的实用性。
