Participants

Reaction Steps

A solution of (S)-3-((S)-1-(3-bromophenyl)ethyl)-6-(4-fluorophenyl)-6-(2-oxopropyl)-1,3-oxazinan-2-one (12 mg, 0.028 mmol) in 3:1 THF/MeOH (4 mL) was cooled to 0° C. NaBH4 (2.1 mg, 2 equiv) was added. After 15 min, the mixture was warmed to rt slowly. After stirring 1.5 h, LC-MS found the reaction completed. The mixture was quenched by water (2 mL), concentrated, and purified by preparative HPLC to afford (6S)-3-((S)-1-(3-bromophenyl)ethyl)-6-(4-fluorophenyl)-6-(2-hydroxypropyl)-1,3-oxazinan-2-one (4.4 mg, 36%). LC-MS (3 min) tR=1.68 min, m/z=458, 460 (M+Na). 1H NMR (CDCl3) 7.36-7.21 (m, 3H), 7.12-6.96 (m, 4H), 6.83 (m, 1H), 5.63 (m, 1H), 2.93 (m, 1H), 1.51 (d, 3H), 1.17 (d, 3H).
