for the synthesis of selectively N-substituted tetra- and pentamethylenediamines 1 (n = 4,5) is described. The method uses N-substituted ω-haloalkanamides 2 as precursors and involves the microwave-promoted conversion into ω-azidocarboxamides 3 and later the reduction of both azido and carboxamide groups with diborane.
描述了一种新的合成选择性N-取代的四亚甲基和五亚甲基二胺1(n = 4,5)的方法。该方法使用N-取代的ω-卤代烷酰胺2作为前体,并涉及微波促进的转化成ω-叠氮羧酰胺3,然后用乙硼烷还原叠氮基和羧酰胺基团。
