Web25 mrt. 2024 · Abstract. β-Amino esters are obtained with high levels of enantioselectivity via the conjugate addition of cyclic amines to unactivated α,β-unsaturated esters. A related strategy enables the kinetic resolution of racemic cyclic 2-arylamines, using benzyl acrylate as the resolving agent. Web23 sep. 2015 · Ion Ghiviriga. Scientist.

Webby Ion Ghiviriga ABSTRACT Asymmetric gamma-hydroxy nitriles are valuable intermediates because hydrolysis of the nitriles can result in an intramolecular cyclization to chiral gamma-lactones, which have a variety of biological uses. WebReported is characterization of the self-assembly of π-conjugated oligomers, molecules studied recently in photovoltaic devices, using variable temperature diffusion ordered spectroscopy (VT-DOSY).
