Reaction Steps

To a solution of 300 mg (1.16 mmole) (2R-cis)-3-heptyloxiranemethanol in 50 ml of DMF was added 2.62 g (6.97 mmole) of pyridinium dichromate. The reaction was allowed to stir overnight under argon. The mixture was then diluted with 150 ml H2O and 20 ml 0.1M HCl and washed three times with 50 ml of Et2O. The combined Et2O layers are dried over MgSO4, filtered and evaporated to afford a white powder. This residue was crystallized from petroleum ether to afford 155 mg of white power, mp 53°-5° C. 1H NMR (CDCl3) δ3.60 (d, 1, J=5 Hz), 3.24 (dd, 1, J=5 12 Hz), 1.6-1.2 (m, 12), 0.88 (t, 3, J=7 Hz). Mass Spectra: M-45(--CO2H)(3.7)141.1, M(100)41.0.
