Synthesis and in vitro and in vivo antifungal activity of the hydroxy metabolites of saperconazole.

Herein we describe the scalable diastereoselective and enantioselective syntheses of eight enantiomers of hydroxy metabolites of saperconazole. The in vitro antifungal activity of the eight stereoisomers (compounds 1-8) was compared against a broad panel of Candida spp. (n=93), Aspergillus spp.
