Abstract
Chiral beta-fluoroamines are increasingly prevalent in medicinal compounds, but there are few efficient methods to access them from achiral starting materials. To address this, a multicomponent organocascade reaction was developed in which chiral alpha-fluoro-beta-amino aldehydes were generated in a single flask from achiral alpha,beta-unsaturated aldehydes (2), using catalyst 12a. Conversions up to 85%, dr's up to 98:2 and ee's up to 99% of the corresponding alcohol (9) were achieved in this reaction.
