This invention is directed towards novel alkylamide derivatives as bradykinin receptor antagonists useful for the treatment of bradykinin modulated disorders such as pain, inflammation, asthma and allergy. Furthermore, the present invention is directed to novel alkylamide derivatives as bradykinin receptor agonists useful for the treatment of bradykinin modulated disorders such as hypertension and the like.

N-Pyrrolylmagnesium halides (1,2) react with alkyl bromoacetates (3a-d) in THF solution to give alkyl 2-pyrrolylacetates (5a-d) in good yields and with very high positional selectivity (C-2:C-3 greater than or equal to 25). The high regioselectivity is rationalized in terms of an increased propinquity between C-2 and the bromoacetate methylene group as a consequence of coordination between magnesium and the carbonyl oxygen of the alkylating agent, (2,5-Dimethylpyrrol-N-yl)magnesium chloride (9) and isopropyl bromoacetate (3c) gave the 3-pyrrolylacetate 10 exclusively. Alkoxycarbonylation of the dianions of the above alkyl pyrrolylacetates with alkyl chloroformates gave the corresponding dialkyl pyrrolylmalonates, two of which (16a and 19) were transformed into the dialkyl 1,2-dihydro-3H-pyrrolo[1,2-a]pyrrole-1,1-dicarboxylates (22 and 20, respectively) with 1,2-dichloroethane under phase transfer conditions. Compound 20 was converted into the powerful nonaddicting analgesic ketorolac (21).

The synthesis and structure-activity relationships of a novel series of aroylpyrrole alkylamindes as potent selective bradykinin 132 receptor antagonists are described. Several members of this series display nanomolar affinity at the B-2 receptor and show activity in an animal model of antinociception. (C) 2003 Elsevier Science Ltd. All rights reserved.
