Pyridine, hydrofluoride (1:1) → (4S)-4-(2-Fluoro-2-methylpropyl)-2-oxazolidinone

Participants

Reaction Steps

The 4-fluoroleucinol can also be synthesized according to Scheme 8. 4,5-Dehydroleucine is converted to (4S)-4-(2-methylprop-2-enyl)-1,3-oxazolidin-2-one as described in the scheme below. This intermediate is then treated with a hydrofluorination reagent such as HF-pyridine to give (4S)-4-(2-fluoro-2-methylpropyl)-1,3-oxazolidin-2-one. Basic hydrolysis (i.e. Ba(OH)2 or NaOH) then affords (2S)-2-amino-4-fluoro-4-methylpentan-1-ol.
