金属卟啉(MP)由于在结构和功能上与氧化酶的血红素辅基相似,因此常用于仿生催化。在这些酶中,卟啉铁主要通过半胱氨酸(细胞色素P450,CYP),组氨酸(过氧化物酶)和酪氨酸(过氧化氢酶)在活性位点与蛋白质结合,作为轴向配体。不同的氧化酶表现出的不同功能性和可变的氧化能力[部分]归因于连接氨基酸以及铁与杂原子之间的关系。通过开发行为类似于CYP酶的MP系统来模仿这种关系的尝试主要集中在掺入氮(N)-杂环。尽管众所周知,不同的酶家族偏爱独特的产物,但硫容易被氧化并易于形成二硫键,因此,硫醇盐大部分尚未开发。在这里,我们报告了我们的发现,这些结果是由间-氯过氧苯甲酸(m -CPBA)通过受不同轴向配体螯合的受阻铁(III)卟啉催化非那西丁,美沙西丁和对乙酰苯胺的仿生氧化而得。9个轴向配体的p K a(2.8-11.2),大小和杂原子身份进行了检查,以更准确地确定影响功能和作用的因素。在大多数情况

The catalytic union of amides, sulfonamides, anilines, imines, or N-heterocycles with a broad spectrum of electronically and sterically diverse alkyl bromides has been achieved via a visible-light-induced metallaphotoredox platform. The use of a halogen abstraction-radical capture (HARC) mechanism allows for room temperature coupling of C(sp3)-bromides using simple Cu(II) salts, effectively bypassing
通过可见光诱导的金属光氧化还原平台实现了酰胺、磺胺、苯胺、亚胺或N-杂环与广谱电子和空间多样化烷基溴的催化结合。卤素提取-自由基捕获 (HARC) 机制的使用允许使用简单的 Cu(II) 盐在室温下耦合 C( sp 3 )-溴化物,有效绕过通常与热诱导 S N 2 或 S相关的过高障碍N 1 N-烷基化。这种区域和化学选择性方案与 >10 类药物相关的N兼容- 亲核试剂,包括已建立的药剂,以及结构多样的伯、仲和叔烷基溴。此外,通过将N-亲核试剂与环丙基溴和未活化的烷基氯(与亲核取代途径不相容的底物)结合,突出了 HARC 方法与传统惰性偶联伙伴结合的能力。初步的机械实验验证了该平台的双重催化、开壳性质,这使得在传统的基于卤化物的N-烷基化系统中无法实现的反应性成为可能。
