Qiu, Youai; Ma, Dengke; Kong, Wangqing; Fu, Chunling; Ma, Shengming published an article in 2014, the title of the article was Regiocontrolled 1,2-migration in cyclization of 1-(indol-2-yl)-3-alkyn-1-ols: (Ph3P)Au+ vs. PtCl4.Related Products of 883526-76-9 And the article contains the following content:
A simple and efficient AuCl(PPh3)/AgBF4- and PtCl4-catalyzed reaction of 1-(indol-2-yl)-3-alkyn-1-ols I [R1 = R2 = R4 = CH3, R3 = Bu; R1 = Et, R2 = R4 = Me, R3 = Bu; R1 = allyl, R2 = H, R3 = Bu, R4 = Me; etc.] occurred smoothly in toluene to form a series of differently polysubstituted carbazole derivatives II. The regioselectivity of the 1,2-migration may be tuned by using different metal catalysts: carbazoles II could be obtained exclusively in the presence of AuCl(PPh3)/AgBF4 via a Wagner-Meerwein type 1,2-alkyl shift, whereas in some cases the use of PtCl4 afforded differently substituted carbazoles III involving a platinum-carbene intermediate. The experimental process involved the reaction of 1,5-Dimethyl-1H-indole-2-carbaldehyde(cas: 883526-76-9).Related Products of 883526-76-9
