found to be very efficient for asymmetric aziridination followed by intramoleculararylation (Friedel–Crafts) reaction to provide a general and direct method for the synthesis of trans-3-amino-4-arylchromans with high regio-, diastereo- (dr > 99:1), and enantioselectivity (up to 95% ee) with moderate yield. trans-3-Amino-4-arylchroman is an advanced intermediate for the synthesis of chromenoisoquinoline
