合成
该化合物可由二亚乙基三胺通过用乙二醇二甲苯磺酸酯的大环化反应制备。[2]
- H2NCH2CH2NHCH2CH2NH2 + 3 TsCl → Ts(H)NCH2CH2N(Ts)CH2CHH2N(H)Ts + 3 HCl
- Ts(H)NCH2CH2N(Ts)CH2CH2N(H)Ts + 2 NaOEt → Ts(Na)NCH2CH2N(Ts)CH2CH2N(Na)Ts
- Ts(Na)NCHH2CH2N(Ts)CH2CH2N(Na)Ts + TsOCH2CH2OTs + → [(CH2CH2N(Ts)]3 + 2 NaOTs
- [(CH2CH2N(Ts)]3 + 3 H2O → [CH2CH2NH]3 + 3 HOTs
