The first asymmetric synthesis of indole alkaloid (+)-subincanadine F was successfully accomplished with the uncommon 7-endo-trig stereoselective radical cyclization as the key step and its absolute configuration was thus assigned.

de via aziridinium ring formation and its reductivering expansion route. Regioselective and stereoselective reductive aziridinium carbon–nitrogen bond cleavage comprising ring expansions was a key step. The (S)-OMOM protection of the hydroxyl moiety adjacent to a benzylic carbon of an in situ formed aziridinium system was necessary for lithium borohydride-induced reductivering expansions, and it
