G. Nicolosi et al., ENZYMATIC ACCESS TO HOMOCHIRAL L-ACETOXY-2-HYDROXYCYCLOHEXANE-3,5-DIENE THROUGH LIPASE-ASSISTED ACETYLATION IN ORGANIC-SOLVENT, Tetrahedron letters, 36(36), 1995, pp. 6545-6546
Enantiotoposelective acetylation of cis-1,2-dihydroxycyclohexa-3,5-die
ne with vinyl acetate in tert-butyl methyl ether, promoted by immobili
zed lipase from Mucor miehei (Lipozyme(R) IM), afforded (1R,2S)-1-acet
oxy-2-hydroxycyclohexa-3,5-diene in good chemical yield and high enant
iomeric excess.
