On August 2, 2019, Maejima, Saki; Yamaguchi, Eiji; Itoh, Akichika published an article.Application of 10472-24-9 The title of the article was Visible Light/Molecular-Iodine-Mediated Intermolecular Spirolactonization Reaction of Olefins with Cyclic Ketones. And the article contained the following:

In this study, intermol. spirolactonization via an iodine/visible-light-mediated C-C/C-O bond formation reaction was developed. The developed reaction proceeded to form quaternary carbon centers via carboesterification between cyclic β-keto esters and olefins, affording spirolactone derivatives, e.g., I, in a single step. In addition, the mechanistic investigation revealed that the generation of iodine radicals from mol. iodine driven by visible-light irradiation is a crucial step. The developed reaction proceeded under milder conditions than previously reported procedures as iodine played a role of a conventional transition-metal catalyst, realizing an environmentally friendly mol. transformation. The experimental process involved the reaction of Methyl 2-cyclopentanonecarboxylate(cas: 10472-24-9).Application of 10472-24-9
