The total syntheses of two of the three dimeric naphthylisoquinoline michellamines - A and C - were achieved by Pd-catalyzed cross-coupling of the appropriate 6'-bromo- or 6'-boronic acid-substituted tetrabenzylated korupsensamine A and B derivatives under nonaqueous conditions, followed by deprotection of the octabenzylated products.
