실험 절차

A solution of {(Z)-4-[(R)-2-oxo-6-((E)-3-oxo-4-phenyl-but-1-enyl)-piperidin-1-yl]-but-2-enyloxy}-acetic acid methyl ester (24.6 mg, 0.064 mmol) in CH3CN (1.5 mL) was added via cannula to hydrido(triphenylphosphine)copper(I) hexamer (125 mg, 0.064 mmol) at −40° C. After 1 h at −40° C., the reaction was allowed to warm to rt. After 3 h at rt, the reaction was quenched by addition of a solution of NH4OH and saturated aqueous NH4Cl (1:1, 6 mL). The mixture was extracted with EtOAc (3×10 mL). The combined organic phase was washed with brine (20 mL), dried (Na2SO4), filtered and concentrated in vacuo. Purification of the residue by flash column chromatography on silica gel (20%→70% EtOAc/CH2Cl2, gradient) afforded 19.6 mg (79%) of the title compound.
