A synthetic route for the preparation of alkynylated saturated N-heterocycles via a sequential combination of a Shono oxidation and a gold(I)-catalyzed alkynylation reaction has been developed. The electrochemical Shono oxidation allowed an efficient access to a variety of N,O-acetals via a direct C−H bond functionalization of cyclic amines. The reaction conditions were amenable with functionalized
