[R′CH(OH)CHCHCO2R], which are ubiquitous structures in biologically active natural products and useful building blocks for organicsynthesis of chiral compounds. From the optically pure (R)-2-(2-benzothiazolylsulfinyl)acetates (>99% ee) prepared by the enzymatic kinetic resolution of (±)-2-(2-benzothiazolylsulfinyl)acetates, opticallyactive 4-hydroxyalk-2-enoates (up to 91% ee) have been obtained in good

In previous studies, we identified promising anti-Trypanosoma cruzi cruzain inhibitors based on thiazolylhydrazones. To optimize this series, a number of medicinal chemistry directions were explored and new thiazolylhydrazones and thiosemicarbazones were thus synthesized. Potent cruzain inhibitors were identified, such as thiazolylhydrazones 3b and 3j, which exhibited IC50 of 200–400 nM. Furthermore
