Participants

Reaction Steps

A solution of (R)-3-((S)-1-(4-bromophenyl)ethyl)-6-(3-hydroxypropyl)-6-phenyl-1,3-oxazinan-2-one (200 mg, 0.462 mmol), tributyl-vinyl-stannane (198 mg, 0.624 mmol), Pd2(dba)3 (23 mg, 0.005 mmol) and BINAP (6.84 mg, 0.011 mmol) in toluene (20 mL) was heated to reflux overnight. The reaction mixture was filtered, and the filtrate was concentrated to give the crude product, which was purified by preparative TLC to give (R)-6-(3-hydroxypropyl)-6-phenyl-3-((S)-1-(4-vinylphenyl)ethyl)-1,3-oxazinan-2-one (50 mg, 30%). 1H NMR (CDCl3): 0.81 (m, 2H), 1.07-1.28 (m, 5H), 1.53 (d, 3H), 1.83-1.97 (m, 4H), 2.22 (m, 3H), 2.83 (m, 1H), 3.55 (m, 2H), 5.09 (m, 1H), 5.21 (m, 1H), 5.58 (m, 1H), 6.63-6.77 (m, 2H), 7.04-28 (m, 13H), 7.43 (m, 2H), 7.68 (m, 1H).
