Procedure: The title compound was prepared as described in General Method 6 from 2.0 mmol of 3-bromo-5,6-dihydro-4-hydroxy-6-(3-methylbutyl)-6-phenyl-2H-pyran-2-one (prepared in example CCC), 2.2 mmol of 2-isopropylbenzenethiol, and 2.2 mmol of piperidine in 30 mL of dichloromethane. The crude product was chromatographed on silica gel, eluting first with chloroform and then with 5% methanol in chloroform, to give the title compound (m.p. 64°-66° C.). 1H NMR (DMSO-d6) δ 0.80 (m, 6 H), 0.95 (m, 1 H), 1.17 (t, 7 H), 1.42 (m, 1 H), 1.93 (m, 2 H), 3.20 (m, 1 H), 3.45 (2 H+H2O), 5.84 (d, 1 H), 6.55 (t, 1 H), 6.93 (t, 1 H), 7.12 (d, 1 H), 7.40 (m, 5 H). The title compound was prepared The crude product was chromatographed on silica gel eluting first with chloroform

Procedure: The title compound was prepared as described in General Method 6 from 1.1 mmol of 5-[5-bromo-3,6-dihydro-4-hydroxy-6-oxo-2-phenyl-2H-pyran-2-yl]pentanoic acid (prepared in example DDD), 1.3 mmol of 2-isopropylbenzenethiol, and 1.3 mmol of piperidine in 20 mL of dichloromethane. The crude product was chromatographed on silica gel, eluting first with 5% methanol in chloroform and then with 9:1:0.5 chloroform:methanol:acetic acid, to give the title compound, (m.p. 145°-146° C.). 1H NMR (DMSO-d6) δ 1.07-1.19 (t plus m, 7 H), 1.25 (m, 1 H), 1.43 (m, 2 H), 1.91 (m, 2 H), 2.15 (t, 2 H), 3.19 (m, 1 H), 3.41 (2 H+H2O), 5.81 (d, 1 H), 6.54 (t, 1 H), 6.93 (t, 1 H), 7.12 (d, 1 H), 7.29-7.44 (m, 5 H). The title compound was prepared The crude product was chromatographed on silica gel eluting first with 5% methanol in chloroform

Procedure: The title compound was prepared as described in General Method 6 from 1.50 mmol of 3-bromo-5,6-dihydro-4-hydroxy-6-phenyl-6-(2-phenylethyl)-2H-pyran-2-one (prepared in example BBB), 1.60 mmol of 2-isopropylbenzenethiol, and 1.60 mmol of piperidine in 30 mL of dichloromethane. The product was triturated with hexane:ether (1:1) to afford a solid. The crude product was chromatographed on silica gel, eluting first with chloroform and then with 5% methanol in chloroform, to give the title compound (m.p. 66°-67° C.). 1H NMR (DMSO-d6) δ 1.16 (t, 6 H), 2.21-2.35 (m, 3 H), 2.60 (m, 1 H), 3.21 (m, 1 H), 3.42 (q, 2 H), 5.88 (d, 1 H), 6.56 (t, 1 H), 6.94 (t, 1 H), 7.13 (m, 4 H), 7.25 (m, 2 H), 7.45 (m, 5 H). The title compound was prepared The product was triturated with hexane:ether (1:1) to afford a solid The crude product was chromatographed on silica gel eluting first with chloroform
