Interaction of phenylsulfonyl-2-aminobenzaldehyde with 2-bromo-1- phenylethanones in the presence of K2CO3 followed by acid-catalyzed dehydration led to the formation of 1-phenylsulfonyl-2-aroylindoles.Copyright Taylor & Francis Group, LLC.
Heterocycles from ylides. Part X.Synthesis of 3-hydroxy-2,3-dihydroindoles by a domino reaction
Cremonesi, Giuseppe,Croce, Piero Dalla,Fontana, Francesco,La Rosa, Concetta
experimental part, p. 873 - 876 (2009/09/28)
A domino reaction between 2-N-phenylsulfonylaminobenzaldehyde (1) and sulfonium ylides (2) leads to 3-hydroxy-2,3-dihydroindoles (3) whose structure was confirmed on the basis of analytical and spectroscopic data.
A direct lithiation route to 2-acyl-1-(phenylsulfonyl)indoles
Jiang, Jun,Gribble, Gordon W.
, p. 2035 - 2040 (2007/10/03)
2-Acyl-1-(phenylsulfonyl)indoles (3, 7-9) are prepared in 75-84% yield from 1-(phenylsulfonyl)indoles (1, 5) in one operation by treatment of the latter with s-butyllithium followed by inverse quenching of the C-2 lithioindoles with carboxylic acid anhydr
Reaction of indole-2,3-dicarboxylic anhydride with grignard reagents: synthesis of 2-acylindoles
Miki, Yasuyoshi
, p. 1143 - 1150 (2007/10/03)
Reaction of indole-2,3-dicarboxylic anhydride with methylmagnesium bromide and phenylmagnesium bromide gave 2-acetyl- and 2-benzoyl-indole-3-carboxylic acids, but with tert-butylmagnesium chloride, 3-pivaloylindole-2-carboxylic acids were obtained as the main products. Treatment of 2-acylindole-3-carboxylic acids with copper chromite in quinoline or potassium hydroxide gave the corresponding 2-acylindoles.
Synthesis of Alkyl-Substituted N-Protected Indoles via Acylation and Reductive Deoxygenation
Ketcha, Daniel M.,Lieurance, Brett A.,Homan, Dominic F. J.,Gribble, Gordin W.
, p. 4350 - 4356 (2007/10/02)
The synthesis of 2-, 3-, and 5-alkyl-1-(phenylsulfonyl)indoles involving Friedel-Crafts acylation followed by reductive deoxygenation is described.The application of this acylation-deoxygenation sequence to 3-acyl-1-(phenylsulfonyl)indoles bearing potenti
A DIRECTED METALATION ROUTE TO THE ZWITTERIONIC INDOLE ALKALOIDS. SYNTHESIS OF SEMPERVIRINE
Gribble, Gordon W.,Barden, Timothy C.,Johnson, David A.
, p. 3195 - 3202 (2007/10/02)
A synthesis protocol involving beta-lithiation of 2-(2-pyridinyl)indoles(45) and subsequent reaction with bromoacetaldehyde leads to the indoloquinolizine (1) ring system.Application of this methodology to 2-(2-pyridinyl)indole 17, which is prepared via Taylor-Boger triazine Diels-Alder annulation chemistry, affords the zwitterionic indole alkaloid sempervirine (3).
