Acetylresorcinol → Acetic acid 3-cyclobutoxy-phenyl ester

참여 물질

반응 단계

Acetic acid 3-hydroxy-phenyl ester (1 ml, 9 mmol) was mixed with cyclobutanol (0.58 g, 8 mmol), triphenylphosphine (2.1 g, 8 mmol) and diisopropyl azodicarboxylate (1.57 ml, 8 mmol) in tetrahydrofuran (20 ml) at 0° C. under a nitrogen atmosphere. The mixture was warmed to room temperature and stirred for 16 hours. The reaction mixture was concentrated in-vacuo the residue was purified by chromatography on silica gel using ethyl acetate in pentane as eluant (gradient from 0:100 to 15:85) to give acetic acid 3-cyclobutoxy-phenyl ester (340 mg).
