Synthesis of chiral tertiary trifluoromethyl alcohols by asymmetric nitroaldol reaction with a Cu(II)-bisoxazolidine catalyst was written by Xu, Hanhui;Wolf, Christian. And the article was included in Chemical Communications (Cambridge, United Kingdom) in 2010.Electric Literature of C11H9F3O3 The following contents are mentioned in the article:
A highly enantioselective and diastereoselective copper(II)-bisoxazolidine catalyzed nitroaldol reaction with aliphatic and aromatic trifluoromethyl ketones is described. This study involved multiple reactions and reactants, such as Ethyl 4-(2,2,2-Trifluoroacetyl)benzoate (cas: 898787-14-9Electric Literature of C11H9F3O3).
Ethyl 4-(2,2,2-Trifluoroacetyl)benzoate (cas: 898787-14-9) belongs to esters. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.Electric Literature of C11H9F3O3
