  The effect of vinyl esters on the enantioselectivity of the lipase-catalysed transesterification of alcohols

  摘要：

  The enantioselectivity of the lipase from Pseudomonas cepacia (PCL) in the transesterification of 2-phenyl-1-propanol I was studied using a series of vinyl 3-arylpropanoates as acyl donors. The most enantioselective transesterification reaction of the alcohol was attained by using vinyl 3-(p-iodophenyl)- or 3-(p-trifluoromethylphenyl)propanoates, with enantiomer ratios, E, of 116 and 138, respectively. Vinyl 3-phenylpropanoate was also effective for the resolution of 1 mediated by lipases from P. fluorescens and porcine pancreas and for the PCL-catalysed transesterification of several 2-phenyl-1-alkanols. The enantiomeric resolution of 1 was practically carried out by the first enantioselective transesterification using PCL and vinyl 3-(p-iodophenyl)propanoate to afford (R)-1 and then the enantioselective hydrolysis of the resultant ester to afford (S)-1.

  N-Mercaptoalkanoyl derivatives of sulfur-containing amino acids were synthesized as candidate angiotensin I converting enzyme (ACE) inhibitors. Among them, N-[3-mercapto-2- (4-methoxybenzyl) propanoyl] -S-ethyl-L-cysteine (5d) was found to be the most potent inhibitor of ACE, with an IC50 value of 0.045μM. The maximum hypotensive effect of this compound was almost equal to that of captopril in anesthetized rats.
