Jillella, Raveendra; Oh, Dong hwan; Oh, Chang Ho published an article in 2018, the title of the article was Di-tert-butyl-hydroxyphenyl phenyl-indolyl methyl aromatic aldehyde prepn via Gold-catalyzed tandem reaction of 2-alkynylanilines followed by 1,6-conjugate addition to p-quinone methides..Quality Control of 2-((4-Methoxyphenyl)ethynyl)aniline And the article contains the following content:
A simple, mild, efficient and chemoselective catalytic method for the straightforward synthesis of an interesting class of 2-aryl/alkyl-substituted-3-diaryl indolyl methanes in high yield was reported. This atom-efficient method proceeded via a gold-catalyzed one-pot sequential intramol. hydroamination (C-N bond formation) of 2-alkynylanilines followed by a 1,6-conjugate addition to p-quinonemethides. The p-quinonemethides, which contain aldehyde functional groups, preferentially participate in 1,6-conjugate addition, while the aldehyde functional group remains unreactive. The experimental process involved the reaction of 2-((4-Methoxyphenyl)ethynyl)aniline(cas: 157869-15-3).Quality Control of 2-((4-Methoxyphenyl)ethynyl)aniline
