Cryptosporidium parvum is an important human pathogen and potential bioterrorism agent. This protozoan parasite cannot salvage guanine or guanosine and therefore relies on inosine5′-monophosphatedehydrogenase (IMPDH) for biosynthesis of guanine nucleotides and hence for survival. Because C. parvum IMPDH is highly divergent from the host counterpart, selective inhibitors could potentially be used

Abstractmagnified imageA catalytic enantioselective hydrogenation of racemic α‐aryloxy aldehydes via dynamic kinetic resolution has been developed by using (diamine)(spirodiphosphine)ruthenium(II) chloride [RuCl2(SDPs)(diamine)] catalysts. Employing this new reaction system a variety of optically active β‐aryloxy primary alcohols were synthesized in high yields and moderate to good enantioselectivities.
