Reaction Steps
To a solution of (3R,4S)-3-ethyl-4-(hydroxymethyl)cyclopentanol (4.00 g, 27.7 mmol) in MeCN (70 mL) and water (30.0 mL) was added potassium bromate (1.487 mL, 29.1 mmol) and CAN (0.760 g, 1.387 mmol). The reaction mixture was heated to about 80° C. After about 2 h, the reaction mixture was cooled to rt and Et2O (100 mL) was added. The organic layer was separated, washed with brine (30 mL), concd in vacuo and purified by chromatography on silica gel eluting with EtOAc/heptane (20-60%) to provide (3R,4S)-3-ethyl-4-(hydroxymethyl)cyclopentanone (2.4 g, 61%) as an oil. 1H NMR (400 MHz, CDCl3) δ 3.79 (dd, J=10.5, 5.3 Hz, 1H), 3.70 (dd, J=10.5, 6.5 Hz, 1H), 2.55-2.44 (m, 1H), 2.41-2.25 (m, 4H), 2.15-2.05 (m, 1H), 1.55-1.65 (m, 2H), 1.43-1.30 (m, 1H), 0.97 (t, J=7.3 Hz, 3H).
