Ag2O-promoted nucleophilic substitution on a common precursor, a chiral non-racemic 2-bromoacyl derivative. Simple variation of nucleophile substituents allows a rapid and stereocontrolled development of new series of derivatives. Some reported compounds showed potent biological activity as growth inhibitors of cancer cell lines and tubulin polymerization inhibitors.
