A note on the Noyori model for chiral amplification in the aminoalcohol-catalyzed reaction of aldehydes with dialkylzinc [PDF]
Journal of the Serbian Chemical Society, 1999 The Noyori model of chiral amplification in the alkylation of aldehydes by means of dialkylzinc, catalyzed by chiral aminoalcohols, is further elaborated.

2D Ising Model for Enantiomer Adsorption on Achiral Surfaces: L- and D-Aspartic Acid on Cu(111)
Entropy, 2022 The 2D Ising model is well-formulated to address problems in adsorption thermodynamics. It is particularly well-suited to describing the adsorption isotherms predicting the surface enantiomeric excess, ees, observed during competitive co-adsorption of ...

Asymmetric Meerwein-Ponndorf-Verley reduction of long chain keto alkanoic acid methyl esters [PDF]
Journal of the Serbian Chemical Society, 2007 3-, 7- and 13-Monoketo tetradecanoic acid methyl esters carrying a keto group at the ends and at the middle of the chain with 14 carbon atoms were reduced by a Meerwein-Ponndorf-Verley reaction in the presence of R-(+)-1,1'-binaphthalene- 2,2'-diol, 1,2 ...
