Lange, Heiko; Bergander, Klaus; Froehlich, Roland; Kehr, Seda; Nakamura, Shuichi; Shibata, Norio; Toru, Takeshi; Hoppe, Dieter published the artcile< Highly enantioselective reactions of configurationally labile epimeric diamine complexes of lithiated S-benzyl thiocarbamates>, Product Details of C19H34O2, the main research area is enantioselective reaction configuration labile epimeric diamine complex lithiation benzylthiocarbamate.
Substitution reactions that employ primary-carbamoyl-protected arylmethanethiols are described. The enantio-determination step was found to occur in the post-deprotonation step as a dynamic thermodn. resolution with a chiral bis(oxazoline) ligand. The configurationally labile lithium complexes were trapped with various electrophiles to yield different substitution products in good to excellent yields and enantiomeric excesses. The absolute configurations of the substitution products were determined, and the stereochem. pathway of the substitution reaction was elucidated for different classes of electrophiles. The temperature-dependent epimerization process was monitored by 1H and 6Li NMR spectroscopy.
