[0305] Step (a): Preparation of 6,7,8,9-tetrahydro-oxyfluorene-3-sulfonic acid
[0306] To a solution of tetrahydrofluorene (4 g, 0.023 mol) in dichloroethane (50 mL) was added sulfur dioxide-DMF complex (6 g, 0.039 mol) in one portion. The reaction mixture was refluxed for 14 hours, cooled and concentrated in vacuo. The resulting crude liquid was dissolved in warm diethyl ether / ethanol and precipitated upon cooling. The solid was collected by filtration, washed with diethyl ether and dried in vacuo to afford the title compound as a pink solid (2.3 g, 40%). 1 HNMR (CDCl 3 )δ7.9(s,1H),7.7(d,1H),7.4(d,1H),2.8(m,2H),2.6(m,2H),2.0-1.8(m,4H)ppm.
[0307] Step (b): Preparation of 6,7,8,9-tetrahydro-oxyfluorene-3-sulfonylchloride
[0317] (S) 2-(6,7,8,9-Tetrahydro-oxyfluorene-3-sulfonylamino)-succinic acid; mp 176-179°C. 1 HNMR (CDCl 3 / DMSO -d 6 )δ7.8(s,1H),7.6(d,1H),7.4(d,1H),5.9(d,1H),3.9(m,1H),2.9-2.5(m,7H),1.9-1.7 (m, 4H)ppm. Using a method similar to that described in Example 1, but replacing D-valine and tert-butyl ester with L-homophenylalanine and methyl ester, and utilizing alkali hydrolysis to prepare the following Compound:

Background of the invention [0001] The present invention relates to novel tricyclic sulfonamide compounds and their derivatives used as medicines, their preparation methods, pharmaceutical compositions comprising these compounds and pharmaceutically acceptable carriers, and medical treatment methods. The novel compounds of the present invention are inhibitors of matrix metalloproteinases such as gelatinase A (MMP-2), collagenase-3 (MMP-13) and stromelysin-1 (MMP-2). More specifically, the novel compounds of the present invention are useful in the treatment of atherosclerotic plaque rupture, aortic aneurysm, heart failure, left ventricular dilatation, restenosis, periodontal disease, corneal ulcer, burn management, decubitus ulcer, wound repair , cancer, inflammation, pain, arthritis, osteoporosis, multiple sclerosis, kidney disease, and other autoimmune or inflammatory diseases that depend on tissue invasion by leukocytes or other activated mobile cells. In addition, the comp...
