催化异戊烯基二磷酸酯和二甲基烯丙基二磷酸酯相互转化的2型异戊烯基二磷酸异构酶(IDI-2)包含FMN的紧密结合分子。为了探测反应的机理,合成了被设计为基于机理的不可逆抑制剂的环丙基和环氧底物类似物,并用嗜热栖热菌(Thermus thermophilus)的IDI-2进行了评估。环丙基类似物是替代底物。环氧类似物是不可逆的抑制剂,k I = 0.37±0.07 min -1,K I = 1.4±0.3μM。LC-MS研究表明形成了环氧化物-FMN加合物。

The rapid assembly of valuable cyclic amine architectures in a single step from simple precursors has been recognized as an ideal platform in term of efficiency and sustainability. Although a vast number of studies regarding cyclic amine synthesis has been reported, new synthetic disconnection approaches are still high in demand. Herein, we report a catalytic radical‐polar crossover cycloaddition to cyclic amine synthesis triggered from primary sulfonamide under photoredox condition. This newly developed disconnection, comparable to established synthetic approaches, will allow to construct β, β‐disubstituted cyclic amine and β‐monosubstituted cyclic amine derivatives efficiently. This study highlights the unique utility of primary sulfonamide as a bifunctional reagent, which acts as a radical precursor and a nucleophile. The open‐shell methodology demonstrates broad tolerance to various functional groups, drug derivatives and natural products in an economically and sustainable fashion.
