  Conformational Structure and Dynamics of Arylmethoxyacetates: DNMR Spectroscopy and Aromatic Shielding Effect

  摘要：

  The ground state conformational geometry and energy of esters of (R)- and (S)-arylmethoxyacetic acids were evaluated from low temperature H-1 and C-13 NMR spectra and by means of MM, AM1, and aromatic shielding effect calculations. In solution, the title compounds are constituted by two rotamers in equilibrium. Rotamer ap has the C-alpha-O and C=O bonds antiperiplanar and rotamer sp (lower in energy by 0.4-1.1 kcal/mol) has these bonds synperiplanar. In both the ap and the sp the aryl ring is ca. perpendicular to the C=O bond and coplanar with the CalphaH bond. Their relative populations and its temperature dependence evaluated by DNMR spectra are in agreement with the stereoselectivity reported for Diels-Alder reactions of dienyl-AMAA esters and support the ''perpendicular model'' proposed to account for that stereoselectivity. For conformations in which the aryl ring shields the alcohol moiety of the ester, calculated ring current shielding increments compare well with experimental shift values obtained from low-temperature NMR spectra and agree with the conformational model used in the Mislow-Dale-Mosher-Trost method for chiral recognition by NMR.

  direct and chemoselective esterification of α-hydroxyacids was developed using a reversible covalent-binding strategy. By taking advantage of acetal chemistry, simple aldehydes can be used to efficiently catalyze the esterification of α-hydroxy carboxylic acids in the presence of β-hydroxyacid moieties or other carboxylic acids in amounts equal to or in excess of the alcohols. A diverse array of α-aryl

  日期：1995.2

  Pig liver acetone powder (PLAP) catalyzed hydrolysis of alkyl α-acetoxy-α-arylacetates produces alkyl (S)-α-aryl-α-hydroxyacetates in 23–80% enantiomeric purities. Enantioselectivity is dependent on the ester group of O-acetylmandelates. Substitution on the aromatic ring results in inferior selectivities. Only acetate group is hydrolyzed by PLAP while the ester functionality is found to be completely
