The racemic tricyclic acyloin (±)-endo-3-hydroxytricyclo[4.2.1.02,5]non-7-en -4-one has been dynamically resolved via the transient formation of the meso-enediol isomer under lipase–triethylamine-mediated kinetic transesterification conditions to give the single chiral acetate (-)-endo-3-acetoxytricyclo[4.2.1.02,5]non-7-en- 4-one, serving as a precursor of (-)-oxodicyclopentadiene, in excellent optical and chemical yields.
