Catalytic Enantioselective and Divergent Total Synthesis of (+)-10-Oxocylindrocarpidine, (+)-Cylindrocarpidine, (−)-<i>N</i>-Acetylcylindrocarpinol, and (+)-Aspidospermine
asymmetric allylation of carbazolones developed in our laboratory. Our syntheses, using a combination of C–H activation, enantioselective catalysis, and collective synthesis, represent the first totalsynthesis of 10-oxocylindrocarpidine and the first asymmetric totalsynthesis of cylindrocarpidine and N-acetylcylindrocarpinol.
