On July 27, 2020, Deichert, Julie A.; Mizufune, Hideya; Patel, Jignesh J.; Hurst, Timothy E.; Maheta, Ashish; Kitching, Mathew O.; Ross, Avena C.; Snieckus, Victor published an article.Synthetic Route of 321-28-8 The title of the article was Expedient Pd-Catalyzed α-Arylation towards Dibenzoxepinones: Pivotal Manske’s Ketone for the Formal Synthesis of Cularine Alkaloids. And the article contained the following:
The general synthesis of diversely substituted dibenzoxepinones by a combined Pd-catalyzed α-arylation and SNAr strategy is reported and applied to the synthesis of Manske’s ketone, a key intermediate en route to the total synthesis of cularine alkaloids. In the course of this work, an unanticipated ring contraction reaction to a xanthone was observed and serves as a caveat for the conditions of the widely used α-arylation reaction. Thus, e.g., o-(2-bromophenoxy)acetophenone â?dibenzoxepinone I (72%) in presence of Pd2(dba)3 and XantPhos, Cs2CO3 as base and toluene as solvent. The experimental process involved the reaction of 1-Fluoro-2-methoxybenzene(cas: 321-28-8).Synthetic Route of 321-28-8
