Triphenylphosphine → HCID 67001595, compound

Participants

Reaction Steps

(3-Hydroxy-1-hydroxymethyl-2,2-dimethyl-propyl)-carbamic acid tert-butyl ester (104 mg, 0.44 mmol) was dissolved in dichloromethane (2.2 mL). Triphenylphosphine (0.115 g, 0.44 mmol) was added followed by azodiethylcarboxylate (0.16 mL, 0.88 mmol). After 30 min additional triphenylphosphine (0.115 g, 0.44 mmol) and azodiethylcarboxylate (0.16 mL, 0.88 mmol) were added and the reaction mixture was stirred for 72 h. The solvent was evaporated and the residue purified by silica gel chromatography (ethyl acetate/hexanes) to give 70 mg (74%) of (4,4-dimethyl-tetrahydro-furan-3-yl)-carbamic acid tert-butyl ester.
