Preparation of 9-Fluoro-5-(1,3-dithia-2-cyclohexylidene)-1,2-dihydro-2,2,4-trimethyl-5H-chromeno[3,4-f]quinoline (Compound 10, Structure 4 of Scheme I, where R4=methyl, R7=R8=R10=R11=H, R9=F, Y=Z=S)
[0081] To a solution of 1,3-dithiane (0.24 g, 2.0 mmol) in THF (10 mL) at −70° C. was added n-BuLi (1.6 M in hexane, 1.3 mL) and the resulting mixture was stirred at −10° C. for 2 h. To the reaction mixture at −70° C. was added 9-fluoro-1,2-dihydro-2,2,4-trimethyl-5-coumarino[3,4-f]quinoline (Compound 11, Structure 1 of Scheme I, where R4=methyl, R7=R8=H, R9=F) (0.12 g, 0.40 mmol) in THF (1 mL). The dark red solution was slowly warmed to −30° C. till the red color faded away and was quenched immediately with water. Extraction with EtOAc and chromatography afforded 9-fluoro-5-(1,3-dithia-2-cyclohexyl)-5-hydroxy-1,2-dihydro-2,2,4-trimethyl-5H-chromeno[3,4-f]quinoline (Compound 12, Structure 3 of Scheme I, where R4=methyl, R7=R8=R10=R11=H, R9=F, Y=Z=S), which was then treated in CH2Cl2 (10 ...

Preparation of 8-methoxy-5-(1,3-dithia-2-cyclohexylidene)-1,2-dihydro-2,2,4-trimethyl-5H-chromeno[3,4-f]quinoline (Compound 13, Structure 4 of Scheme I, where R4=methyl, R7=R9=R10=R11=H, R8=methoxy, Y=Z=S)
[0082] This compound was prepared in a similar fashion as that described in Example 1 from 1,3-dithiane and 8-methoxy-1,2-dihydro-2,2,4-trimethyl-5-coumarino[3,4-f]quinoline (Compound 14, Structure 1 of Scheme I, where R4=methyl, R7=R9=H, R8=methoxy) as a yellow solid: 1H-NMR (400 MHz, CDCl3) 7.39 (d, J=8.2, 1H), 7.20 (d, J=2.9, 11H), 7.07 (d, J=8.9, 1H), 6.73 (dd, J=8.9, 2.9, 1H), 6.63 (d, J=8.2, 1H), 5.47 (s, 1H), 4.1 (bs, 1H), 3.82 (s, 3H), 3.04-2.98 (m, 1H), 2.89-2.78 (m, 2H), 2.68-2.64 (m, 1H), 2.16-2.03 (m, 2H), 1.99 (s, 3H), 1.41 (s, 3H), 1.25 (s, 3H).

Preparation of 7,9-difluoro-5-(1,3-dithia-2-cyclohexylidene)-1,2-dihydro-2,2,4-trimethyl-5H-chromeno[3,4-f]quinoline (Compound 15, Structure 4 of Scheme I, where R4=methyl, R8=R10=R11=H, R7=R9=fluorine, Y=Z=S)
[0083] This compound was prepared in a similar fashion as that described in Example 1 from 1,3-dithiane and 7,9-difluoro-1,2-dihydro-2,2,4-trimethyl-5-coumarino[3,4-f]quinoline (Compound 16, Structure 1 of Scheme I, where R4=methyl, R7=R9=fluorine, R8=H) as a yellow solid: 1H-NMR (500 MHz, CDCl3) 7.31 (d, J=8.2, 1H), 7.14-7.11 (m, 1H), 6.72 (ddd, J=10.1, 8.2, 2.7, 1H), 6.62 (d, J=8.2, 1H), 5.48 (s, 1H), 4.18 (bs, 1H), 3.07-3.01 (m, 1H), 2.92-2.82 (m, 2H), 2.72-2.67 (m, 1H), 2.18-2.07 (m, 2H), 1.99 (d, J=1.2, 3H), 1.41 (s, 3H), 1.28 (s, 3H).
