Regiospecific generation and application of 3-lithiomethyl-2-methyl-1-phenylpyrazolin-5-one as 1,3-binucleophile in aromatic annelation: A novel approach for synthesis of 1,2-disubstituted indazolones and their condensed analogs

The enolate anion 5A generated by deprotonation of 2,3-dimelhyl- 1-phenylpyrazolin-5-one is shown to undergo highly regioselective γ-1,4-addition to α-oxoketene dithioacelals followed by cycloaromatizalion in the presence of boron trifluoride etherate to afford wide range of novel substituted and condensed indazolones in good yields.

We report the discovery of potent agonists for the human formyl-peptide-like 1 receptor (hFPRL1). These compounds did not act at a closely related receptor denoted human formyl peptide receptor (hFPR) up to 10 mu M concentration. Recent studies have indicated that agonizing this receptor may promote resolution of inflammation. In an exploratory study, a novel hFPRL1 agonist showed efficacy in a mouse ear inflammation model following oral administration. (c) 2006 Elsevier Ltd. All rights reserved.
