Wen, Li-Rong; Shen, Qiang-Yu; Guo, Wei-Si; Li, Ming published an article in 2016, the title of the article was Copper-catalyzed tandem arylation-cyclization of 2-alkynylaryl isothiocyanates with diaryliodonium salts: an efficient synthesis of thiochromeno[2,3-b]indoles.Recommanded Product: 2-((4-Methoxyphenyl)ethynyl)aniline And the article contains the following content:
A catalytic tandem arylation-cyclization approach using 2-alkynylphenyl isothiocyanates with diaryliodonium salts was described. The reaction was performed under mild conditions and thiochromeno[2,3-b]indoles, e.g., I were obtained in moderate to good yields. This tandem protocol involved chemoselective S-arylation, regioselective 5-endo-trig cyclization and Friedel-Crafts-type cyclization processes. Two C-C bonds, one C-S bond, and two heterocyclic rings were formed in a single step. Preliminary mechanistic studies indicated that carbocation mechanism was involved. The experimental process involved the reaction of 2-((4-Methoxyphenyl)ethynyl)aniline(cas: 157869-15-3).Recommanded Product: 2-((4-Methoxyphenyl)ethynyl)aniline
