Sodium hydride → 6-allyl-3-((S)-3,3-dimethylbutan-2-yl)-6-(4-fluorophenyl)-1,3-oxazinan-2-one

Participants

Reaction Steps

To a solution of (S)-3,3-dimethylbutan-2-yl(3-(4-fluorophenyl)-3-hydroxyhex-5-enyl)carba mate (2.2 g, 6.27 mmol) in dry THF (25 mL) was added NaH (752 mg, 18.80 mmol) at 0° C. under N2, and the mixture was stirred at it overnight. The reaction was quenched with water, and the mixture was extracted with EtOAc. The combined organic layer was washed with brine, dried over Na2SO4, filtered and concentrated to afford the crude product, which was purified by chromatography to give two isomers of 6-allyl-3-((2S)-3,3-dimethylbutan-2-yl)-6-(4-fluorophenyl)-1,3-oxazinan-2-one.
