Lv, Honggui; Shi, Jingjing; Wu, Bo; Guo, Yujuan; Huang, Junjun; Yi, Wei published an article in 2017, the title of the article was One-pot synthesis of 2,3-difunctionalized indoles via Rh(III)-catalyzed carbenoid insertion C-H activation/cyclization.Recommanded Product: 65417-22-3 And the article contains the following content:
The first Rh(III)-catalyzed carbenoid insertion C-H activation/cyclization of N-arylureas R1NHC(O)R (R = N(CH3)2, NHCH3; R1 = naphth-1-yl, 2-CH3C6H4, 3-ClC6H4, 4-CH3(O)CC6H4, etc.) and α-diazo β-keto esters R2C(O)C(=N2)C(O)R3 [R2 = H, Me, Ph, CH2OCH3, CH2CH3; R3 = C(O)OCH2CH3, C(O)OCH2C6H5, ((OCH3)2)P(O), etc.] was reported. The redox-neutral reaction has the following features: good to excellent yields, broad substrate/functional group tolerance, exclusive regioselectivity, and no need for addnl. oxidants or additives, which render this methodol. as a more efficient and versatile alternative to the existing methods for the synthesis of 2,3-difunctionalized indoles e.g., I. The experimental process involved the reaction of Methyl 2-methyl-1H-indole-3-carboxylate(cas: 65417-22-3).Recommanded Product: 65417-22-3
