Abstract Several selectively protected spermidine homologues were synthesized via cyanoethylation reaction of monoprotected diamines, subsequent protection of their secondary amino group, hydrolysis of nitrile to primary amide function, and final Hofmann degradation of amides to amines with the aid of iodosobenzene diacetate (PIDA). The protected spermidine homologues may be directly used in the synthesis
摘要 通过单保护二胺的氰乙基化反应、仲氨基的后续保护、腈水解为伯酰胺官能团以及酰胺在二乙酸碘苯酯 (PIDA) 的帮助下最终霍夫曼降解为胺,合成了几种选择性保护的亚精胺同系物。受保护的亚精胺同系物可直接用于多胺酰胺的合成或可进一步官能化。
