2-IMIDAZOLINE, 2-OXAZOLINE, 2-THIAZOLINE, AND 4-IMIDAZOLE DERIVATIVES OF METHYLPHENYL, METHOXYPHENYL, AND AMINOPHENYL ALKYLSULFONAMIDES AND UREAS AND THEIR USE

The present invention concerns novel compounds represented by the Formula: STR1 wherein: A is R 1 q (R 3 R 60 N). sub.m (Z)(NR 2) n ; m and q are each 0 or 1, with the proviso that when q is 1, m is 0 and when q is 0, m is 1; Z is C=O or SO 2 ; n is 1 with the proviso that, when Z is C=O, m is 1; X is--NH--,--CH 2--, or--OCH 2--; Y is 2-imidazoline, 2-oxazoline, 2-thiazoline, or 4-imidazole; R 1 is H, lower alkyl, or phenyl, with the proviso that, when R 1 is H, m is 1; R 2, R 3, R 60 are each independently H, lower alkyl, or phenyl; R 4, R 5, R. sup.6, and R 7 are each independently hydrogen, lower alkyl,--CF. sub.3, lower alkoxy, halogen, phenyl, lower alkeny, hydroxyl, lower alkylsulfonamido, or lower cycloalkyl, wherein R. sup.2 and R 7 optionally may be taken together to form alkylene or alkenylene of 2 to 3 atoms in an unsubstituted or optionally substituted 5-or 6-membered ring, wherein the optional substituents on the ring are halo, lower alkyl, or--CN, with the proviso that, when R 7 is hydroxyl or lower alkylsulfonamido, then X is not--NH--when Y is 2-imidazoline. The compounds include pharmaceutically acceptable salts of the above. In the above formula A may be, for example, (R 1 SO 2 NR 2--), (R. sup.3 R 60 NSO 2 NR 2--), or (R 3 R 60 NCONR 2--). The invention also includes the use of the above compounds, and compositions containing them, as alpha 1A/1L agonists in the treatment of various disease states such as urinary incontinence, nasal congestion, priapism, depression, anxiety, dementia, senility, Alzheimer's, deficiencies in attentiveness and cognition, and eating disorders such as obesity, bulimia, and anorexia.

SYNTHESIS OF 2,1-BENZISOTHIAZOLINE 2,2-DIOXIDE DERIVATIVES

Base-induced (NaOH/DMSO) intramolecular SNAr of fluorine in methanesulfonanilide 1 derivatives leads to 6-nitro-2,1-benzisothiazoline derivatives 2. meta-Nitro methanesulfonanilides 3 in the presence of tert-BuOK in DMF were transformed into 4-
