On July 4, 2019, Shershnev, Ivan; Dar’in, Dmitry; Chuprun, Sergey; Kantin, Grigory; Bakulina, Olga; Krasavin, Mikhail published an article.Safety of 3-Acetyldihydrofuran-2(3H)-one The title of the article was The use of α-diazo-γ-butyrolactone in the Buchner-Curtius-Schlotterbeck reaction of cyclic ketones: A facile entry into spirocyclic scaffolds. And the article contained the following:
The first example of the Buchner-Curtius-Schlotterbeck reaction of cyclic ketones with a stabilized cyclic diazo compound partner is described. The approach towards spirocyclic scaffolds has been exemplified with readily available α-diazo-γ-butyrolactone. The reaction proved to be viable with BF3·OEt2 as the preferred catalyst and displayed substantial sensitivity to the size of the cyclic ketone. The experimental process involved the reaction of 3-Acetyldihydrofuran-2(3H)-one(cas: 517-23-7).Safety of 3-Acetyldihydrofuran-2(3H)-one
