Lipase-mediated enantioselective acylation of alcohols with functionalized vinyl esters: acyl donor tolerance and applications
摘要:
Enzymatic acylation is commonly used for the kinetic resolution of alcohols and amines. The simple acyl group introduced during the enzymatic reaction is Usually removed or replaced by another group. Retention of more complex acyl moieties as part of the target structures would be a more efficient strategy. We have studied the enantioselective acylation of a model alcohol substrate, 1-phenylethanol, with vinyl esters bearing various functionality on the acyl moieties in the presence of three lipases (Candida antarctica, Candida rugosa and Burkholderia cepacia) frequently used in organic synthesis. C. antarctica lipase is the most versatile lipase for this type of biotransformations. We applied this strategy to the synthesis of a protein kinase C ligand and a natural product, phoracantholide.

targeting the C1 domain of these two kinases. Herein, we report the resolution of the racemates by enantioselective semi-preparative HPLC. The attribution of the absolute configuration (AC) of homochirals 1 was performed by NMR, via methoxy-α-trifluoromethyl-α-phenylacetic acid derivatization (MTPA or Mosher's acid). Moreover, the match between the experimental and predicted electronic circular dichroism
