专利号:US-3901899-A 优先权日:1973-04-27 标题 :Synthesis of indoles from anilines and intermediates therein 发明人:GASSMAN PAUL G 权利人:UNIV OHIO STATE RES FOUND 摘要:Preparing indoles and intermediates therefor by reacting an Nhaloaniline with a Beta -carbonylic hydrocarbon sulfide to form an azasulfonium halide, reacting the azasulfonium halide with a strong base to form a thio-ether indole derivative, and then reducing the thio-ether indole, e.g. with Raney nickel, to form the indole compound. When an acetal or ketal of the Beta carbonyl hydrocarbon sulfide is used, the azasulfonium salt is treated with a base, and then with an acid to form the thio-ether indole derivative. When an Alpha -ethyl- Beta -carbonylic hydrocarbon sulfide is used, the resulting azosulfonium salt reacts with strong base to form a thio-ether indolenine derivative, which on reduction with Raney nickel or complex metal hydrides yields 3-substituted indoles. The aniline may be an aminopyridine to form an aza-indole compound in the process. The azasulfonium salts and thio-ether indole or thio-ether indolenine derivatives can be isolated and recovered from their respective reaction mixtures. The thio-ether-indole and thio-ether indolenine derivatives are useful as intermediates to make the indoles without the thio-ether group. The indoles are known compounds having a wide variety of uses, e.g., in making perfumes, dyes, amino acids, pharmaceuticals, agricultural chemicals and the like.
