An efficient, highly enantioselective, organocatalyticMichaeladdition reaction of aldehydes with trifluoroethylidene malonates is described. The asymmetric reaction provided highly optically pure β-trifluoromethyl aldehydes which can be conveniently transformed into 4,4,4-trifluoromethyl butyric acid and trifluoromethyl substituted δ-lactones without loss in enantioselectivity.
