Ag-Catalyzed Asymmetric Interrupted Barton-Zard Reaction Enabling the Enantioselective Dearomatization of 2- and 3-Nitroindoles was written by Yuan, Wei-Cheng;Chen, Xin-Meng;Zhao, Jian-Qiang;Zhang, Yan-Ping;Wang, Zhen-Hua;You, Yong. And the article was included in Organic Letters in 2022.Synthetic Route of C39H38N3O2P This article mentions the following:

Authors disclose a Ag-catalyzed asym. interrupted Barton-Zard reaction of α-aryl substituted isocyanoacetates with 2- and 3-nitroindoles, which enables the dearomatization of nitroindoles and hence offers rapid access to an array of optically active tetrahydropyrrolo[3,4-b]indole derivatives bearing three contiguous stereogenic centers including two tetrasubstituted chiral carbon atoms with pretty outcomes (up to 99% yield, 91:9 dr and 96% ee). The synthetic potential of the protocol was showcased by the gram-scale reaction and versatile transformations of product. In the experiment, the researchers used many compounds, for example, 2-(Diphenylphosphino)-N-((S)-(6-methoxyquinolin-4-yl)((1S,2S,4S,5R)-5-vinylquinuclidin-2-yl)methyl)benzamide (cas: 1630973-03-3Synthetic Route of C39H38N3O2P).
