The asymmetric dearomatization–addition reaction of halomethyloxazoles and halomethylindoles with aldehydes is realized in the presence of a carbazole-based bisoxazoline CrCl2 complex to afford the corresponding enantioenriched, hydroxylated oxazoline and indoline products. The observed excellent chemo-, regio-, diastereo- and enantioselectivities are notable advantages of this protocol. The strategy established in this study is expected to find application in the synthesis of azaheterocycles with biological significance and useful functionalities.
