The invention relates to cyclic N-[1,3,4]-thiadiazol-2-yl-benzene sulfonamides and to their physiologically acceptable salts and physiologically functional derivatives showing PPARdelta or PPARdelta and PPARgamma agonist activity.
What is described are compounds of the formula I,
in which the radicals are as defined, and their physiologically acceptable salts and processes for their preparations. The compounds are suitable for the treatment and/or prevention of disorders of fatty acid metabolism and glucose utilization disorders as well as of disorders in which insulin resistance is involved and demyelinating and other neurodegenerative disorders of the central and peripheral nervous system.
Kinetic resolution of (+/-)-trans- and (+/-)-cis-2-phenylcyclopentanamine is effectively performed by lipase B from Candida antarctica, (CALB)-catalyzed aminolysis reaction. Whereas reaction between (+/-)-trans-2-phenylcyclopentanamine and ethyl acetate proceeds with a very high E value (>200) and conversion (50%), the corresponding acetylation of ()-cis-2-phenylcyclopentanamine happens with low E value (16) and conversion (28%). Nevertheless, this problem is overcome using other acyl donors such as (+/-)-1-phenylethyl and (+/-)-cis-2-phenylcyclopentyl methoxyacetates. The influence of the acyl donor on the CALB-catalyzed aminolysis of (+/-)-cis-2-phenylcyclopentanamine is also studied. (C) 2003 Elsevier Ltd. All rights reserved.
