Electrochemically constructing C-N and N-C-N bonds provides an economical sustainable alternative to conventional chemosynthesis. Herein, a hierarchically ordered open superstructure of N-doped carbon isolated with accessible three-coordinated Zn single-atom sites is explored for efficient electrocatalytic coupling. Benefiting from the distinctive structural merits, this catalyst enables preparation bonded compounds methanol amines. Notably, Faradaic efficiency selectivity N,N,N',N'-tetramethyldiaminomethane reach up 77% 96% at 0.8 V, respectively. Further integrating aminoalkylation reaction, electro-thermo cascade synthesis electrochemically obtained serving as unique reagent, leading specific set organonitrogen (dimethylamino)methyl substituent, including topotecan hydrochloride, anti-tumor drug, high yield 95%. Furthermore, in situ spectroscopic characterization calculations unveil that under-coordinated Zn-N3 play pivotal role stabilizing key *CH2O intermediate, thereby facilitating subsequent nucleophilic addition
