The first totalsynthesis of (−)-bicubebin A, and two previously unreported dilignans, (−)-bicubebin B and (+)-bicubebin C has been achieved through the dimerization of (−)-cubebin, confirming the structure and absolute stereochemistry of (−)-bicubebin A. Analysis of the data for (−)-bicubebin B showed it matched that of reported compound (−)-cis-cubebin. The NMR data of the subsequently synthesized

Stereocontrolled total syntheses of the (2S,3R)- and (2R,3S)-isomers of the non-chlorinated analog of cyanobacterin, a potent photosynthesis inhibitor, were achieved. Since both the (2R,3R)- and (2S,3S)-isomers of this compound had been previously synthesized from the same starting material, a systematic strategy for the synthesis of all stereoisomers could be established.
