The racemic tricyclic acyloin
(±)-endo-3-hydroxytricyclo[4.2.1.0
2,5
]non-7-en
-4-one has been dynamically resolved via the transient formation
of the meso-enediol isomer under
lipaseâtriethylamine-mediated kinetic transesterification conditions
to give the single chiral acetate
(-)-endo-3-acetoxytricyclo[4.2.1.0
2,5
]non-7-en-
4-one, serving as a precursor of (-)-oxodicyclopentadiene, in
excellent optical and chemical yields.
