The present invention is directed to practical high-yielding synthetic processes for preparing 3,4-disubstituted-thiazolidin-2-ones, which do not compromise the absolute stereochemical integrity of the compounds. The present invention is also directed to novel compounds of 3,4-disubstituted-thiazolidin-2-ones. The compounds prepared by the present invention are useful in the synthesis and manufacture of compounds (such as latrunculins and/or their analogs) for treating diseases or conditions associated with inhibiting actin polymerization.

A novel Au-catalyzed tandem cycloisomerization/oxidation of homopropargyl alcohols was developed. Various γ-lactones can be accessed readily by utilizing this strategy. Notably, the mechanism of this reaction is distinctively different from the related Ru-catalyzed reactions where the ruthenium vinylidene intermediate was proposed.
