Enantioselective construction of vicinal stereogenic quaternary centers by dialkylation: Practical total syntheses of (+)- and meso-chimonanthine

All three stereoisomers of the hexacyclic 3a,3a'-bispyrrolidino[2,3- b]indoline moiety found in complex indole alkaloids can be prepared, as illustrated by total syntheses of meso-chimonanthine (1) and (+)- chimonanthine (2). A rare example of high diaste
