실험 절차

2,3-Dideoxy-3-C-methyl-5-O-tert-butyldimethylsilyl-D-erythro-pentono-1,4-lactone (1.4 g, 6.13 mmol) was treated with tetra-n-butylammonium fluoride (8.7 mL of a 1.0M solution in tetrahydrofuran, 8.7 mmol) for 90 minutes at room temperature. The reaction mixture was evaporated, and the crude product subjected to flash silica gel chromatography eluting initially with 15% acetone in hexane and subsequently with 25% acetone in hexane. Pure title compound was obtained as an oil; yield 710 mg (89%); 1H NMR (400 MHz, CDCl3): δ1.16 (d, 3H), 2.21 (dd, 1H), 2.50 (m, 1H), 2.72 (dd, 1H).
