3-dihydro-6H-pyran-3-ones (5, 13) are described. Separation into enantiomers was carried out by classical resolution via diastereomeric camphanic acid ester intermediates (14, 15). A new method for cleavage of the 2-(trimethylsilyl)ethyl protecting group in the presence of acid and base sensitive functionality is reported.
