Participants

Reaction Steps

(R)-4-(6-hydroxynaphthalen-2-yl)-4-methyloxazolidin-2-one (Example 4, 0.0509 g, 0.000209 mol) was dissolved in tetrahydrofuran (3.00 mL, 0.0370 mol) in a capped 40 mL EPA vial equipped with a magnetic stir bar. Cis-4-tert-butylcyclohexanol (0.0392 g, 0.000251 mol) was added, followed by triphenylphosphine (0.0878 g, 0.000335 mol) and the reaction was heated to reflux. Diisopropyl azodicarboxylate (0.0659 mL, 0.000335 mol) was added and the reaction was heated at reflux overnight with stirring. TLC analysis showed that the reaction was complete. The mixture was concentrated under vacuum. The resulting product was purified by flash chromatography (0-30% EtOAc in methylene chloride) to give 0.3141 g of the title compound (66% yield).
