A panel of natural aliphatic tertiary alkaloids (R₃N) were directly converted to R₃N⁺–NH⁻ (without the need to prepare protected aminimides R₃N⁺–NR′⁻ followed by deprotection) by [Mn(TDCPP)Cl]-catalysed N-amination reaction, with O-(2,4-dinitrophenyl)hydroxylamine as the nitrogen source, in up to 98% yields under mild reaction conditions.

通过[Mn（TDCPP）Cl]催化的N胺化反应，从天然脂肪族叔生物碱（R3N）直接制备未保护的氨基酰亚胺（R3N + -NH-）。

天然脂肪族叔胺生物碱的面板（R ₃ N）直接转化为R ₃ Ñ ⁺ -NH ^- （无需制备保护的胺化酰亚胺- [R ₃ Ñ ⁺ -NR' ^-接着脱保护）由[Mn（上TDCPP）氯在温和的反应条件下，以O-（2,4-二硝基苯基）羟胺为氮源，经[ - ]催化的N-胺化反应，收率高达98％。
