Significance

Trifluoromethylacetaldimines, generated in situ from the corresponding N,O-acetals, undergo 1,2-addition of arylboroxines under palladium catalysis to generate a variety of R-(trifluoromethyl)arylmethylamines with good to high enantio­selectivity and yield.

Comment

The reported protocol is very versatile since it proceeds without the exclusion of ambient air and moisture. Moreover, several functional groups are tolerated, and readily available N,O-acetals synthesized from trifluoroaldehyde are used as starting materials.
