Asymmetric Synthesis of Aminochromanes via Intramolecular Indium-Mediated Allylation of Chiral Hydrazones
The asymmetric intramolecular indium-mediated cyclization reaction delivers chromanes with excellent diastereoselectivity (68–91% yield, dr >99:1). The reaction was efficient for aryl substrates with both electron withdrawing or donating groups. Carboxylic acid additives were found to be necessar...
