実験手順

The title compound was prepared as described in General Method 9 from 6-cyclohexyl-4-hydroxy-6-[2-(4-hydroxy-phenyl)-ethyl]-5,6-dihydro-pyran-2-one (prepared in Example NN; 210 mg, 0.664 mmol), toluene-4-thiosulfonic acid S-(2-tert-butyl-4-hydroxy-5-methyl-phenyl) ester (prepared in Example RRR; 256 mg, 0.730 mmol), K2CO3 (367 mg, 2.655 mmol), and DMF (4 mL). The reaction was stirred at room temperature overnight and then worked up in the usual fashion. The crude product was flash chromatographed using CH2Cl2 :MeOH (98:2) to give the desired product as a solid, m.p. 100°-103° C. 1H NMR (DMSO-6) δ 1.0-2.1 (m, 13 H), 1.45 (s, 9 H), 1.80 (s, 3 H), 2.5-2.6 (2 H+DMSO), 2.7 (d, 1 H), 2.9 (d, 1 H), 6.6-6.7 (d, s, 3 H), 6.77 (s, 1 H), 6.9 (d, 2 H), 9.01 (s, 1 H), 9.13 (s, 1 H).
