Reaction Steps
The mixture of spiro[5.5]undecan-3-ol (166.0 mg, 0.0009866 mol), (R)-4-(6-hydroxynaphthalen-2-yl)-4-methyloxazolidin-2-one (200.0 mg, 0.0008222 mol), and triphenylphosphine (259 mg, 0.000987 mol) in tetrahydrofuran (7 mL, 0.08 mol) was heated to reflux, and diisopropyl azodicarboxylate (0.194 mL, 0.000987 mol) was added dropwise and was stirred and refluxed for overnight. The mixture was taken up into methylene chloride and subjected to chromatography purification with EtOAc/hexane (10:90 to 80:20) to give product (4R)-4-methyl-4-(6-(spiro[5.5]undecan-3-yloxy)naphthalen-2-yl)oxazolidin-2-one as a white solid (324 mg, 100%). LCMS Rf=2.34 min 394.45 ([M+1]+, 100%).
