An efficient two-step synthesis of 1-aryl-2-dimethylaminoethanols 4 is described, consisting of oxazolidine 3 generation from the cycloaddition of an azomethine ylide to an aldehyde, followed by reductive ring-opening.

Herein we report the asymmetric organocatalyzed method for the Friedel–Craftsreaction between activatedphenols and trihaloacetaldehydes. A three-phase screening including 41 compounds was employed to identify a catalyst structure based on 3,5-dinitrobenzamide of 9-amino-epi-cinchonidine as the lead catalytic molecule. Under the optimized reaction conditions, the above catalyst offered trihalohydroxyalkylated
