Syntheses and Biological Evaluation of Iriomoteolide 3a and Analogues

DOI:10.1002/anie.200903379

(RCM) approach has led to the stereocontrolled synthesis of iriomoteolide 3a, a smaller but equally cytotoxic congener of amphidinolides. Chemical editing of the molecule has provided non‐natural analogues which have comparable anticancer activity to that of the natural product, thereby allowing the iriomoteolides to be used as probe molecules in chemical biology.

Bi-functional cobalt-containing catalysts useful for making stereo specific compounds and compositions, along with methods of making, and uses thereof in the syntheses of optically pure β-lactones from aldehydes and ketene are described. Precursors, intermediates, compositions, and particular features of the use if the compositions, such as high enantiomeric selectivity, high yield and low mole percent of catalyst useful are provided.
