A convergent stereoselective synthesis of (4R,15R,16R,21S)- and (4R,15S,16S,21S)-rollicosin and squamostolide was accomplished via a Pd-catalyzed cross-coupling reaction. The inhibitory activity of these compounds was examined with bovine heart mitochondrial NADH-ubiquinone oxidoreductase. These compounds showed a remarkably weak inhibitory activity compared to ordinary acetogenins such as bullatacin. Our results indicate that to maintain potent inhibitory effect, the hydroxylated lactone cannot substitute for the hydroxylated mono- or bis-THF rings with a long alkyl chain that can be seen in ordinary acetogenins.
