Herein, we report a sodium tert-butoxide-promoted reduction of N-heteroarenes using ammonia borane and dimethyl sulfoxide (DMSO) under mild reaction conditions. This method demonstrates broad functional group compatibility across diverse N-heteroarene substrates. Notably, substituting DMSO with deuterated DMSO-d6 enables the synthesis C3-deuterated 1,2,3,4-tetrahydroquinolines remarkable positional selectivity. Mechanistic investigations indicate that protons are derived from both DMSO. strategy establishes novel environmentally benign approach for (deuterated) N-heterocycles, offering practical advantages in terms operational simplicity sustainable
