Abstract
Enantiomers of cis,cis-decahydro-2-naphthyl-N-n-butylcarbamate show stereo-specific inhibition for acetylcholinesterase and butyrylcholinesterase. For both inhibition reaction, (2S,4aR,8aS)-cis,cis-decahydro-2-naphthyl-N-n- butylcarbamate is more potent than (2R,4aS,8aR)-cis,cis-decahydro-2-naphthyl-N-n-butylcarbamate. Optically pure (2S,4aR,8aS)-(-)- and (2R,4aS,8aR)-(+)-cis,cis-decahydro-2-naphthols are resolved by the porcine pancreatic lipase-catalyzed acetylation of decahydro-2-naphthols with vinyl acetate. Absolute configurations and the enantiomeric excess values of (2S,4aR,8aS)-(-)- and (2R,4aS,8aR)-(+)-cis,cis-decahydro-2-naphthols are determined from the (19)F NMR spectra of their Mosher's ester derivatives. We fail to resolve (2S,4aR,8aR)- and (2R,4aS,8aS)-trans,cis-decahydro-2-naphthols from the porcine pancreatic lipase-catalyzed acetylation of decahydro-2-naphthols with vinyl acetate.
