Abstract Several orthogonally protected spermidine and norspermidine derivatives have been synthesized via cyanoethylation of monoprotected 1,4‐butanediamine (putrescine) or 1,3‐propanediamine followed by protection of their secondary amino groups and final reduction of the nitriles with lithium aluminum hydride in etheral solution at 0°C, thus affording protected norspermidine or spermidine that may
摘要 通过单保护的 1,4-丁二胺(腐胺)或 1,3-丙二胺的氰乙基化,然后保护它们的仲氨基,最后在醚溶液中用氢化铝锂还原腈类,合成了几种正交保护的亚精胺和去甲精胺衍生物。在0°C,从而提供可用于合成多胺酰胺或可进一步官能化的受保护的去甲精胺或亚精胺。
