Participants

Reaction Steps

To a suspension of NaH (180 mg, 4.4 mmol) in THF (5 mL) was added a solution of (R)-6-(3-hydroxypropyl)-6-phenyl-3-((S)-1-(4-vinylphenyl)ethyl)-1,3-oxazinan-2-one (800 mg, 2.2 mmol) in THF (10 mL) at 0° C. The resulting mixture was stirred for 30 min. Then PMBCI (520 mg, 3.3 mmol) was added to the above mixture. The mixture was stirred for 3 h. The reaction was quenched with aqueous NH4Cl solution. The organic phase was separated, and concentrated to give the crude (R)-6-(3-(4-methoxybenzyloxy)propyl)-6-phenyl-3-((S)-1-(4-vinylphenyl)ethyl)-1,3-oxazinan-2-one, which was used for the next step without purification (460 mg, 46%).
