This invention relates to a method of preparing (3R,4R)-3-hydroxy-4-hydroxymethylpyrrolidine, a key intermediate compound for the synthesis of certain inhibitor compounds, including the step of enzyme catalysed enantioselective esterification of an hydroxy group of an hydroxypyrrolidine. The invention further relates to a method for preparing (3S,4S)-3-hydroxy-4-hydroxymethylpyrrolidine, which is the enantiomer of (3R,4R)-3-hydroxy-4-hydroxymethylpyrrolidine.

A number of 7-substituted-1-tert-butyl-6-fluoroquinolone-3-carboxylic acids and 7-substituted-1-tert-butyl-6-fluoro-1,8-naphthyridine-3-carboxylic acids have been prepared and tested for antibacterial activities. Among those the 7-aminopyrrolidinyl 20b and the 7-diazabicyclo naphthyridine 18b are the most potent compounds in vitro and in vivo. Physicochemical data and acute toxicity are also discussed
Chemokine receptor antagonists, in particular, bicyclic diamine compounds of Formula (I) that act as antagonists of chemokine CCR2 and CCR3 receptors including pharmaceutical compositions and uses thereof to treat or prevent diseases associated with monocyte accumulation, lymphocyte accumulation or leucocyte accumulation are described herein.
