On February 5, 2021, Wang, Huihong; Cao, Fei; Gao, Weiwei; Wang, Xiaodong; Yang, Yuhang; Shi, Tao; Wang, Zhen published an article.Reference of 2-(Oxiran-2-ylmethyl)isoindoline-1,3-dione The title of the article was Pd(II)-Catalyzed Annulation Reactions of Epoxides with Benzamides to Synthesize Isoquinolones. And the article contained the following:
Epoxides as alkylating reagents were unprecedentedly applied in Pd(II)-catalyzed C-H alkylation and oxidative annulation of substituted benzamides to synthesize isoquinolones I [R = 7-Me, 6-t-Bu, 6,8-di-OMe, etc.; R1 = Me, n-pentyl, Bn, etc.; R2 = OMe, OEt, OBn, etc.] rather than isochromans, which was accomplished through alerting the previously reported reaction mechanism by the addition of oxidant and TEA. Under these conditions, various isoquinolones were prepared with yields up to 92%. In addition, this methodol. was successfully employed in the total syntheses of rupreschstyril, siamine, and cassiarin A in an expedient fashion. The experimental process involved the reaction of 2-(Oxiran-2-ylmethyl)isoindoline-1,3-dione(cas: 5455-98-1).Reference of 2-(Oxiran-2-ylmethyl)isoindoline-1,3-dione
