Sulfanyl radical addition to alkynyl azides: An insight into vinyl radical cyclization onto the azido function
Montevecchi, Pier Carlo,Navacchia, Maria Luisa,Spagnolo, Piero
, p. 7913 - 7916 (1997)
5-Exo-Cyclization of 2-sulfanylvinyl radicals 16 and 21 is a fast process which prevents intramolecular addition to the sulfanyl aromatic ring and hydrogen abstraction. In contrast, the 2-sulfanylvinyl radicals 3 and 9 are reluctant to add to their alipha
Aniline-initiated and Br?nsted acid-catalyzed one-pot reaction toward 2-aryl-3-sulfenylindoles by using α-aminocarbonyl compounds and primary amines with RSSR

A highly novel method of direct synthesis of 2-aryl-3-sulfenylindoles in moderate to good yields was developed via one-pot tandem reaction of readily available α-aminocarbonyl compounds and catalytic amount of benzenamines with RSSR.
Synthesis of Polysubstituted 3-Chalcogenated Indoles through Copper(I) Iodide-Catalyzed Three-Component Domino Reactions
Gou, Rui,Zhang, Yi,Wu, Sheng-Wei,Liu, Feng
, p. 207 - 212 (2019/01/14)
Polysubstituted 3-chalcogenated indoles were synthesized by a three-component, one-pot, domino reaction of a N -(2-bromophenyl)trifluoroacetamide, a 1-alkyne, a disulfides or diselenides, CuI, and proline in DMF. In this process, tandem Sonogashira coupling, N-cyclization, and sulfenyl/selenyl electrophilic substitution occurred sequentially and smoothly to form the anticipated products in good to excellent yields (20 examples; 65-96%). Notably, no palladium catalyst was used in this catalytic system, supporting its cost effectiveness and potential industrial application.
Method for directly synthesizing indole by using nitrile
-
Paragraph 0047-0049, (2018/12/13)
The invention discloses a method for directly synthesizing indole by using nitrile. The method is characterized in that a 2-iodotoluene derivative is served as a substrate, anhydrous copper sulfate, potassium tert-butoxide, a cyanophenyl derivative and the 2-iodophene derivative are mixed according to the molar ratio of (0.02-0.1): (2-4): (5-20):1, reaction is carried out for 4-48 hours at 60-105DEG C in a solvent, petroleum ether/dichloromethane/ethyl acetate are mixed according to the volume ratio of (20-5):10:1 so as to be served as an eluent, and separation is carried out by using a silica gel column so as to obtain a target product. The method has the advantages that the operation is simple, the conditions are mild, the yield is high, and the method is a green and novel synthetic method.
