Ozone → HCID 58109689, compound

Participants

Reaction Steps

To a solution of (R)-6-(3-(tert-butyldimethylsilyloxy)propyl)-6-phenyl-3-((S)-1-(4-vinylphenyl)ethyl)-1,3-oxazinan-2-one (40 mg, 0.08 mmol) in CH2Cl2 (15 mL) was treated with ozone at −78° C. until the mixture turned blue. The system was then flushed with oxygen to move excess ozone. NaBH4 (12.2 mg, 0.32 mmol) was added to the mixture in portions at rt, and the mixture was stirred overnight at rt. The reaction was quenched by water, and the layers were separated. The aqueous layer was extracted with CH2Cl2 (2×). The organic layer was combined, washed with brine, dried over anhydrous Na2SO4 and concentrated to give the crude product, which was purified by preparative TLC to give (R)-6-(3-(tert-butyldimethylsilyloxy)propyl)-3-((S)-1-(4-(hydroxylmethyl)phenyl)ethyl)-6-phenyl-1,3-oxazinan-2-one (10 mg, 25%). 1H NMR (CDCl3): 0.00 (s, 4H), 0.09 (s, 2H), 0.87 (s, 8H), 1.28 (s, 4H), 1.53 (d, 3H), 1.98 (d, 2H), 3.53 (m, 2H), 4.25 (m, 1H), 4.98 (m, 1H), 4.61 (m, 1H), 5.71 (m, 1H), 6.90 (m, 1H), 7.12-7.38 (m, 10H).
