Chemoselective Transfer Hydrogenation of Enamides Using Ru Pincer Complexes for the Synthesis of α-Amino Acids
Pinheiro, Danielle L. J.,Nielsen, Martin
, p. 5419 - 5423 (2022/03/14)
The chemoselective reduction of enamides to α-amino acids with iPrOH and EtOH as H-donors and solvents catalyzed by Ru pincer complexes is demonstrated. A range of α-amino acids is synthesized in good to excellent yields. Applications, large scale, and a one-pot experiment are also reported. Finally, deuterium-labeling experiments show high regioselectivity between the α-and β-positions of the alkene unit.

experimental part, p. 1175 - 1180 (2012/01/06)
A new and practical promoter system for one-pot, efficient, chemoselective synthesis of 4-arylidene-2-phenyl-5(4H)-oxazolones using [(C14H 24N4)2W10O32]-[bmim] NO3 under solvent-free conditions is described. The present work opens up a new and ecofriendly synthetic route to Erlenmeyer-Ploechl adducts from primary benzyl alcohols in a one-pot operation.

Di[1,6-bis(3-methylimidazolium-1-yl)hexane] decatungstate dihydrate ([C6(MIm)2]2W10O32. 2H2O) as a new family of polyoxometalate-based dicationic ionic liquids (POM-DIL) is synthesized and employed as a novel and powerful heterogeneous catalyst in the synthesis of 4-arylidene-2-phenyl-5(4)-oxazolones (azlactones) under ultrasound-assisted solvent-free condition. On the basis of the results, the products were obtained in excellent yields under mild condition. Utilization of easy work-up and purification make it very interesting from an economic perspective. Moreover, a recycling study confirmed that the catalyst can be reused multiple times without significant loss of its activity.

, p. 136 - 139 (2007/10/02)
The IR spectra of a number of azlactones and their structural analogs, viz., azlactams, in solutions in carbon tetrachloride and in chloroform and in the solid phase were obtained.The character of the interaction of the carbonyl group of the heteroring with substituents with different electronic natures has a substantial effect on the frequencies of the stretching vibrations of the carbonyl group and the azomethine and ethylene bonds.The carbonyl frequencies were subjected to correlation analysis, and high conductivity of the electronic effects of substituents in the 2-phenyl-4-arylideneoxazol-5-one series was ascertained.
