Stereoselective Synthesis of γ‐(Acyloxy)carboxylic Acids and γ‐Lactones Featuring the Switch of Stereopreference of Candida antarctica Lipase B in Sodium γ‐Hydroxycarboxylate Homologues
Scalable protocols of straightforward synthesis of enantiomeric gamma-(acyloxy)carboxylic acids and gamma-lactones are presented. The key step is lipase-catalyzed stereoselective acylation of gamma-hydroxycarboxylic acid sodium salt in organic solvent followed by acidification of the product, extrac...

Scalable protocols of straightforward synthesis of enantiomeric gamma-(acyloxy)carboxylic acids and gamma-lactones are presented. The key step is lipase-catalyzed stereoselective acylation of gamma-hydroxycarboxylic acid sodium salt in organic solvent followed by acidification of the product, extraction and acidic relactonization of the unreacted enantiomer. The mixture of gamma-(acyloxy)carboxylic acid and gamma-lactone is separated either by extraction with solution of sodium bicarbonate or by distillation. A switch of enantioinduction of Candida antarctica lipase B along homologous nucleophiles from R configuration of gamma-hydroxyhexanoic acid salt to S configuration of the C7 and longer-chain homologues has been disclosed. Both enantiomers of gamma-(acyloxy)pentanoic acids; gamma-(acetyloxy)octanoic and -nonanoic acids with S configuration; [(1S,5R)-5-(chloroacetyloxy)cyclopent-2-en-1-yl]acetic acid and enantiomeric gamma-lactones derived from them were prepared with e. r. > 98.5/1.5.
