Catalytic Asymmetric Chemodivergent C2 Alkylation and [3+2]-Cycloaddition of 3-Methylindoles with Aziridines
Highly enantioselective C2 alkylation and inverse-electron-demand [3 + 2]-cycloaddition of 3-methylindoles with 2,2′-diester aziridine were accomplished. The chemodivergent synthesis provided an access to two kinds of chiral indole derivatives in good yields and stereoselectivities in the presence of the chiral N,N’-dioxide/Tm(OTf)(3) or N,N’-dioxide/Ho(OTOf)(3) complexes. An eight-coordinated mode of N,N’-dioxide/Tm(OTf)(3) complex was confirmed by X-ray crystal diffraction to interpret the roles of additives H2O and 1,4-dioxane. In addition, the control experiments indicated that the substituent of the indole nitrogen atom determined the conversion patterns in the divergent reactions.
