A Pd- and norbornene-catalyzed domino procedure has been developed to synthesize indoline compounds. This reaction provides efficient access to indolines by employing aryl iodides with aziridines as new electrophiles. The transformation is scalable and tolerates a range of functional groups.

A set of pyranocyclopentaindolines: Tetracycles representing the ABCD partial structures of the fungal indole diterpenes janthitrem B, JBIR-137, and shearinine G were synthesized starting from indoline. The hydroxylated western section of janthitrem B was obtained in eight steps and 10 % overall yield.
