Expeditious Synthesis of Multisubstituted Quinolinone Derivatives Based on Ring Recombination Strategy

supporting information, p. 244 - 248 (2019/12/30)
We achieved a concise construction of 3-substituted quinolinone derivatives based on a ring recombination strategy. In this process, seven transformations involving two types of cyclization proceeded in one pot to afford various quinolinone derivatives in good to excellent chemical yields (up to 98%).
One-pot photo-reductive N-alkylation of aniline and nitroarene derivatives with primary alcohols over Au-TiO2

We report the photo-catalytic N-alkylation of aniline by Au-TiO 2. We successfully alkylate aniline with several primary alcohols. The combined selectivities of mono- and di-alkylated products were always in excess of 70% and dependent on the alkylating alcohol used. A one-pot reaction from nitrobenzene was found to be possible with several substrates. Preliminary experiments showed that this approach could be adopted for the production of lactams using terminal amino-alcohols. The Royal Society of Chemistry 2013.
Surfactant Control of the Ortho/Para Ratio in the Bromination of Anilines. 2.
Cerichelli, Giorgio,Mancini, Giovanna,Luchetti, Luciana
, p. 3797 - 3802 (2007/10/02)
We report the bromination of some N,N-disubstituted anilines (N-ethyl-N-methylaniline, N,N-diethylaniline, N-butyl-N-methylaniline, 1-phenylpyrrolidine, 1-phenylpiperidine) both in aqueous suspension of cetyltrimethylammonium tribromide (CTAB3) and in homogeneous solution (CHCl3).In the presence of surfactant we observed a regioselectivity different from that observed in homogeneous conditions.The regioselectivity seems to depend on the nature of the substituents on the nitrogen of the aniline as well as on the temperature.An explanation based on specific interactions between the aniline and the packed structure of the aggregate is proposed.
Oxybromination Catalysed by the Heteropolyanion Compound H5PMo10V2O40 in an Organic Medium: Selective para-Bromination of Phenol
Neumann, Ronny,Assael, Igal
, p. 1285 - 1287 (2007/10/02)
Selective bromination of phenol and its derivatives and the bromination of ketones and alkenes have been achieved by oxybromination at ambient conditions catalysed by the mixed addenda heteropolyanion compound H5PMo10V2O40, which is dissolved in a nonpolar chlorohydrocarbon solvent by complexation with tetraglyme.
