oxy-aminomethylation reaction of diazo compounds has been developed, providing the α-hydroxy-β2-amino acidderivatives with quaternary carbon centers in moderate to excellent yields. Importantly, the readily available N,O-acetals have been employed as efficient bifunctionalization reagents to react with copper carbene intermediates, leading to the concurrent incorporation of an alkoxy and an iminium group into one
