The synthesis of the penta-N-protected polyamine thermopentamine (PA 3343, 1a, tert-butyl N-[4-benzyl-16-diallylamino-13-(pyridine-2-suilfonyl)-9-trifluoroacetyl-4,9,13-triazahexadec-1-yl]-carbamate), containing five different N-protecting groups is described. These protecting groups include tert-butoxycarbonyl, benzyl, trifluoroacetyl, diallyl, and pyridine-2-sulfonyl. In spite of the syntheses of
五氮原子保护的多胺热五胺(PA 3343,1a,叔丁基N- [4-苄基-16-二烯丙基氨基-13-(吡啶-2-甲磺酰基)-9-三氟乙酰基-4,9,13)的合成描述了含有五个不同的N-保护基的-(三氮杂十六烷基-1-基]-氨基甲酸酯)。这些保护基包括叔丁氧羰基,苄基,三氟乙酰基,二烯丙基和吡啶-2-磺酰基。尽管合成了特定的多胺衍生物,但已研究了选择性除去这些基团中的每一个的方法。
