Synthesis of (9R)- and (9S)-10-fluorodecan-9-olide (fluoro-phoracantholide I) first lipase-catalyzed enantioselective esterification of β-fluoroalcohols
摘要:
Synthesis of both enantiomers of fluoro-phoracantholide I, namely (9S)-10-fluorodecan-9-olide ((9S)-(-)-1) and (9R)-10-fluorodecan-9-olide (9R)-(+)-1, has been achieved through lipase-catalyzed enantioselective acetylation of methyl 10-fluoro-9-hydroxydecanoate (2a) with acetic anhydride in the presence of Lipase Amano PS (Pseudomonas cepacia). The higher homologue, methyl 11-fluoro-10-hydroxyundecanoate (2b) has also been resolved. These enzymatic resolutions by acetylation of omega-fluoro-(omega-1)-hydroxyalkanoic acid esters of long-chain fatty acids represent the first lipase-catalyzed enantioselective esterifications of beta-fluoroalcohols.
