Abstract
Abstract Per-N-tosylated 3,8-diaza-1,10-decanediamine (9), 4,9-diaza-1,12-dodecanediamine (spermine) (10) and 3,6,9,14,17,20-hexaaza-1,22-docosanediamine (11) were prepared by treating mono-BOC-protected, per-N-tosylated 1,2-ethanediamine (5), 1,3-propanediamine (6) and triethylenetetraamine (7), respectively, with 1,4-dibromobutane and removing the BOC-protecting groups at 100–120 °C.
