Abstract
Aqueous HF promotes the translactonization of silyloxy β-lactones
into β-hydroxy or α,β-unsaturated γ-
and δ-lactones. The reaction is studied from a theoretical
point of view and applied to the racemic synthesis of two natural
bioactive δ-lactones.
Key words
silylketene - lactone - transition state - HF - translactonization.

Typical Procedure:
4-Hydroxy-5-pentyl dihydrofuran-2-one 6:
[23 ]
To
a solution of β-lactones 2 (4/1
mixture of diastereomers: 250 mg, 0.9 mmol) was added aq HF (1 mL). After
4 h stirring at 50 °C, the reaction was extracted
with ether (4 × 4 mL). The organic phases were dried over
MgSO4 and concentrated in vacuo. A purification by flash chromatography
(petrol ether:ether 1:1) yielded hydroxy lactone 6 (150
mg, 0.87 mmol, 97%) as a 4/1 mixture of 2 diastereomers.

Geometries of reactants, intermediates
and products were determined by minimization of energy with respect
to all geometric parameters. Transition states were located by minimizing
the gradient norm of the energy and characterized by one, and only
one, negative eigenvalue of the Hessian matrix. Finally, transition
states reported were shown to belong to the studied reaction by
Intrinsic Reaction Coordinate (IRC) for semiempirical and ab initio calculations.

The relative stereochemistry of the
major diastereomer of β-lactones 11 was
deduced from the one of Prelactone B. It is however consistent with
the 1,3-induction generally observed in β-lactone formation.
