Gao, Wen-Chao,Hu, Fei,Huo, Yu-Ming,Chang, Hong-Hong,Li, Xing,Wei, Wen-Long
supporting information, p. 3914 - 3917 (2015/08/18)
A general method for the synthesis of oxazolines and oxazoles was developed through I2-catalyzed C-O bond formation and dehydrogenation with the same oxidant, TBHP. By simply tuning reaction bases, either oxazolines or oxazoles were selectively
An efficient L-proline catalyzed four-component synthesis of β-acetamido ketones and esters
Singh, Neetu,Singh, Satish Kumar,Singh, Krishna Nand
, p. 915 - 921 (2013/08/23)
An environmentally benign synthesis of p-acetamido carbonyl compounds has been achieved in high yields by one-pot multicomponent condensation of aryl aldehyde, acetyl chloride, acetonitrile/benzonitrile and enolisable ketone/ester in the catalytic presenc
Three-component one-pot reaction for the synthesis of β-amide ketones
Luo, Yan-Ping,Chen, Qiong
, p. 532 - 537 (2013/07/26)
β-amide ketones were synthesised by a three-component one-pot reaction of phenylacetylene, aldehydes, and amides in anhydrous acetonitrile containing trifluoroacetic acid and acetic acid in the presence of AlCl3 catalyst. The title compound structures were identified by 1H NMR, 13C NMR, MS, and elemental analysis.
Cuso4 - 5h2o: A novel, green, reusable, and environmentally friendly catalyst for the one-pot, four-component synthesis of β-acetamido carbonyl compounds

experimental part, p. 705 - 713 (2011/12/21)
Multicomponent reactions for the synthesis of β-acetamido carbonyl compounds have been gained considerable attention in organic synthesis. In this articles, aromatic aldehydes have been employed in a one-pot reaction with enolizable ketones, acetonitrile,
Metal-free chiral phosphoric acid or chiral metal phosphate as active catalyst in the activation of N -acyl aldimines
Terada, Masahiro,Kanomata, Kyohei
scheme or table, p. 1255 - 1258 (2011/07/06)
Whether metal-free chiral phosphoric acid or chiral metal phosphate functions as an active catalyst was confirmed in three reactions. In the aza-Friedel-Crafts and aza-ene-type reactions, a metal-free chiral phosphoric acid, namely, a chiral Bronsted acid
Asymmetric amplification in phosphoric acid catalyzed reactions
Li, Nan,Chen, Xiao-Hua,Zhou, Shi-Ming,Luo, Shi-Wei,Song, Jin,Ren, Lei,Gong, Liu-Zhu
supporting information; experimental part, p. 6378 - 6381 (2010/12/19)
Aneeamp: Asymmetric amplification in reactions catalyzed by phosphoric acids arose from the formation of less soluble supramolecular structures (see scheme; O red, P yellow, C gray, H white) of the racemic phosphoric acids that participate in hydrogen bon
VB1-Al2O3-catalyzed one-pot condensation of aromatic ketone, aromatic aldehyde, and amide
Lei, Min,Ma, Lei,Hu, Lihong
experimental part, p. 4746 - 4749 (2010/09/20)
A novel and green approach for the efficient synthesis of β-amido ketones using VB1-Al2O3 as a heterogeneous catalyst for the first time from an aldehyde, enolizable ketones, and an amide in EtOH is described. The present methodology has several advantages from the economical and environmental points of view, such as simple procedure, low catalyst loading, high atom economy, and good yields.
An efficient, one-pot, multicomponent synthesis of β-acetamido carbonyl compounds using cyanuric chloride in an aqueous medium
