A Cu-catalyzed and 4-OH-TEMPO-mediated sequential dehydrogenation/aza-Michael addition/annulation cascade reaction for the construction of N-alkyl 2-arylindoles I (R = H, 2-F, 3-OMe, 4-Cl, etc.; R1 = H, F, Cl, OMe, C(O)OCH3; R2 = H; R3 = H, Cl; R2R3 = -CH=CHCH=CH-; R4 = Ph, Me, pyridin-3-yl, thiophen-2-yl, etc.) and from facilely available saturated ketones R4C(O)CH2CH3 and 2-arylethynylanilines 2-RC6H4CC-4-R1-5-R2-6-R3C6HNH2 was described. This reaction shows high regioselectivity and tolerates a variety of functional groups. Moreover, 3-alkyl-substituted indoles II (R5 = Bu, tert-Bu, pentyl, propyl) can also be obtained when using 2-alkylethynylanilines 2-R5CCC6H4NH2 as starting materials. In the part of experimental materials, we found many familiar compounds, such as 4-Chloro-2-iodoaniline(cas: 63069-48-7SDS of cas: 63069-48-7)
4-Chloro-2-iodoaniline(cas: 63069-48-7) belongs to anime. Left-handed and right-handed forms (mirror-image configurations, known as optical isomers or enantiomers) are possible when all the substituents on the central nitrogen atom are different (i.e., the nitrogen is chiral). With amines, there is extremely rapid inversion in which the two configurations are interconverted.SDS of cas: 63069-48-7
