反応手順
A mixture of tetrahydro-4H-pyran-4-one (6-1) (5.17 g, 51.7 mmol), prop-2-en-1-ol (1.00 g, 17.2 mmol), allylPalladium Chloride dimer (0.157 g, 0.430 mmol), Xantphos (0.498 g, 0.861 mmol), and DL-proline (0.595 g, 5.17 mmol) in DMSO (35 mL) was degassed (2×pump/N2) and heated to 70° C. overnight. The mixture was cooled to rt and partitioned between water and Et2O. Extracted with Et2O. The combined organics were washed with 1:1 brine:water, dried (anhd. Na2SO4), filtered, and concentrated. The residue was purified by column chromatography to give the title compound. 1H NMR (500 MHz, CDCl3) δ 5.70-5.80 (m, 1H), 5.01-5.09 (m, 2H), 4.13-4.22 (m, 2H), 3.72-3.79 (m, 1H), 3.43 (t, 1H, J=11.2 Hz), 2.52-2.66 (m, 3H), 2.39-2.47 (m, 1H), 1.99-2.07 (m, 1H).
