Dagar, Anuradha; Guin, Soumitra; Samanta, Sampak published an article in 2018, the title of the article was AgSbF6-Catalyzed Tandem Reaction of 2-Alkynylanilines with Cyclic Enynones: Efficient access to 3-Furo[3,2-c]chromenylindoles and Related Scaffolds.Application In Synthesis of 2-((4-Methoxyphenyl)ethynyl)aniline And the article contains the following content:
A simple, mild, catalytic and efficient method for the straightforward synthesis of an interesting class of a range of 2-aryl/alkyl-substituted-3-(2-aryl/alkyl-4H-furo[3,2-c]chromen-4-yl)-1H-indoles I [R = H, Bn; R1 = C6H5, (CH2)3CH3, 4-CH3C6H4, etc.; R2 = C6H5, (CH2)3CH3, 4-CH3C6H4, etc.; X = H, F, OCH3; Y = H, F, CH3, OCH3] in good to high yields is reported for the first time. This atom-efficient method proceeds via AgSbF6-catalyzed one-pot sequential intramol. hydroamination (C-N bond formation) of 2-alkynylanilines 5-X-2-R1CCC6H3NHR followed by Friedel-Crafts alkylation/oxa-cyclization (creation of new C-C and C-O bonds) reaction between in situ generated 2-substituted indoles and several cyclic enynones II and 2-(phenylethynyl)cyclohex-2-enone. The experimental process involved the reaction of 2-((4-Methoxyphenyl)ethynyl)aniline(cas: 157869-15-3).Application In Synthesis of 2-((4-Methoxyphenyl)ethynyl)aniline
