A highly enantioselective amido–functionalized allylation of aldoxime derivatives was achieved in water using O-Boc oximes as substrates under Zn(OH)2-chiral aminophenol catalysis. The products could be transformed into N-hydroxy-γ-lactam or 1,2-oxazinan-6-one, through an acidic treatment or a protection-acidic treatment sequence, respectively.
