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
