Reaction Steps

A mixture of (RS)-2-benzyloxymethyl-2,3-dihydro-4H-pyran-4-one (0.82 g, J. Org. Chem., 44, 811 (1979)) in ethanol (15 ml) containing 10% Pd-C (0.089 g) and triethylamine (10 drops) was hydrogenated until NMR spectroscopy indicated almost complete reaction. The solution was evaporated and the residue purified by silica-gel MPLC [25% EtOAc/hexanes] and then bulb-to-bulb distillation [220° C./2 mmHg] to give the title ketone (0.47 g, 56%).
