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. This study involved multiple reactions and reactants, such as 4-Benzyloxyphenol (cas: 103-16-2Application of 103-16-2).
4-Benzyloxyphenol (cas: 103-16-2) belongs to ethers. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.Application of 103-16-2
