On May 20, 2022, Nandi, Shantanu; Mondal, Shuvam; Jana, Ranjan published an article.Application In Synthesis of Phenyl Salicylate The title of the article was Chemo- and regioselective benzylic C(sp3)-H oxidation bridging the gap between hetero- and homogeneous copper catalysis. And the article contained the following:
An expedient synthesis of privileged seven-membered lactones, dibenzo[c,e]oxepin-5(7H)-one through a highly chemoselective benzylic C(sp3)-H activation was disclosed. Remarkably, the formation of widely explored six-membered lactone via C(sp2)-H activation was suppressed under the present conditions. The reaction proceeded smoothly on use of inexpensive metallic copper catalyst and di-tert-Bu peroxide (DTBP). Owing to the hazards of stoichiometric DTBP, further, a sustainable metallic copper/rose bengal dual catalytic system coupled with mol. oxygen replacing DTBP was developed. A 1,5-aryl migration through Smiles rearrangement was realized from the corresponding diaryl ether substrates instead of expected eight-membered lactones. The present methodol. was scalable, applied to the total synthesis of cytotoxic and neuroprotective natural product alterlactone. The catalyst was recyclable and the reaction could be performed in a copper bottle without any added catalyst. The experimental process involved the reaction of Phenyl Salicylate(cas: 118-55-8).Application In Synthesis of Phenyl Salicylate
