  Photoinduced electron transfer cyclizations of aryl-linked phthalimides

  摘要：

  The photochemistry photochemistry of arene-linked phthalimides incorporating the carboxylate or thioether donor group was investigated. Simple N-phthalimidophenyl alkanoates exclusively gave photoreduction (CO2H/H-exchange) products. In contrast, omega-phthalimido-meta-phenoxy carboxylates underwent photodecarboxylative cyclizations in yields of 6-48%. Likewise, catechol-linked derivatives furnished analogue cyclization products in 18-38% yield. Using the photodecarboxylation protocol, macrocyclic target compounds with ring sizes up to 17 could thus be realized. Two model phthalimides containing a thioether branch at the ortho-position of the arene-linker gave the analogue seven-membered cyclization products in yields of 28% and 35%, respectively.

  development of a novel intermolecular oxidative amination reaction, a synthetic transformation that involves the simultaneous functionalization of both a N-H and C-H bond, is described. The process, which is mediated by an I(III) oxidant and contains no metal catalysts, provides a rapid and green method for synthesizing protected anilines from simple arenes and phthalimide. Mechanistic investigations

  描述了一种新型分子间氧化胺化反应的发展，这是一种合成转化，涉及同时对 NH 和 CH 键进行功能化。该过程由 I(III) 氧化剂介导，不含金属催化剂，为从简单的芳烃和邻苯二甲酰亚胺合成受保护的苯胺提供了一种快速、绿色的方法。机理研究表明，该反应是通过邻苯二甲酰亚胺对芳族自由基阳离子的亲核攻击进行的，这与已报道的其他 I(III) 胺化反应的亲电芳族胺化相反。证明了这种新反应在合成各种取代苯胺衍生物中的应用。

  The unprecedented transformation of a wide range of synthetically appealing phthalimides into amides in a single-step operation has been achieved in high yields and short reaction times using a ruthenium catalyst. Mechanistic studies revealed a unique, homogeneous pathway involving five-membered ring opening and CO2 release with water being the source of protons.
