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.
Physical characteristics and polarographic reduction mechanism of some oxazolones
Ismail, M. I.
, p. 1886 - 1892 (2007/10/02)
The redox potential (ΔE1/2), electron affinity (EA), ionization potential (IP), coulomb repulsion integral (J12), and electronic transition energy (ECT) of several oxazolone derivatives in DMF were computed.A linear correlation was shown to exist between ΔE1/2 and ECT.The polarographic reduction was investigated in ethanolic-Theil buffer solutions.At pH /= 7.2, two waves were obtained representing the uptake of 2- and 4-electron steps respectively.In alkaline media, a third wave appeared seemingly a result of the hydrolysis of oxazolones.The rate of hydrolysis was determined and the electrode mechanism was elucidated and confirmed via spectrophotometric and coulometric analysis. Key words: oxazolones, polarography, electrochemistry, electrode reaction, spectrophotometry, redox potential.

Catalytic hydrogenation of oximes (I-V) over Raney nickel yields the N-benzoylaminoalcohols (VI-X), instead of the expected amines.
