  Lipase-catalyzed enantioselective esterification or hydrolysis of 1-O-alkyl-3-O-tosylglycerol derivatives. Practical synthesis of (S)-(+)-1-O-hexadecyl-2,3-di-O-hexadecanoylglycerol, a marine natural product

  摘要：

  Racemic 1-O-alkyl-3-O-tosylglycerol derivatives were resolved by acylation with palmitic anhydride in the presence of Pseudomonas fluorescens lipase in organic media. The reverse reaction, the enzymatic hydrolysis of 1-O-alkyl-2-O-palmitoyl-3-O-tosylglycerols in isopropyl ether saturated with water was also highly stereoselective. An efficient and simple synthesis of the naturally occurring (S)-(+)-1-O-hexadecyl-2,3-di-O-hexadecanoylglycerol based on this process is reported.
