The room temperature radical decarboxylative allylation of N-protected α-amino acids and esters has been accomplished via a combination of palladium and photoredox catalysis to provide homoallylic amines. Mechanistic investigations revealed that the stability of the α-amino radical, which is formed by decarboxylation, dictates the predominant reaction pathway between competing mechanisms.
通过钯催化和光氧化还原催化相结合的方法,实现了N-保护的α-氨基酸和酯的室温自由基脱羧烯丙基化反应,从而得到高烯丙基胺。机理研究表明,由脱羧反应形成的α-氨基自由基的稳定性决定了竞争机制之间的主要反应途径。
