The present invention is directed to 5,8-disubstituted-[1,2,4]triazolo[1,5- a]pyridinyl and 5,8-disubstituted-imidazo[1,2-a]pyridine derivatives, pharmaceutical compositions containing them and their use in the treatment of disorders and conditions modulated by the enteropeptidase enzyme.
In this paper, we describe investigations into the use of cinchona alkaloid-derived quaternary ammonium phase-transfercatalysts for the asymmetric alkylation of a benzophenone-derived glycine-imine. Utility of this process is demonstrated by the enantioselectivesynthesis of a range of α-aminoacid esters.

new class of Cinchona alkaloid-derived quaternary ammonium phase-transfercatalysts bearing a N-anthracenylmethyl function are presented. These catalysts show high stereocontrol in the asymmetric alkylation of a benzophenone-derived glycine-imine, and application of this process to the enantioselectivesynthesis of a range of α-aminoacid esters (e.e. 67–94%) is investigated.

secondary metabolite aspergillomarasmine A (AMA) has recently been identified as an inhibitor of metallo‐β‐lactamases NDM‐1 and VIM‐2. Described herein is an efficient and practical route to AMA and its related compounds by a sulfamidate approach. In addition, a series of derivatives has been prepared and tested for biological activity in an effort to explore preliminary structure activity relationships.
