Abstract
Earlier unknown racemic β-methylspermidine (β-MeSpd) and γ-methylspermidine (γ-MeSpd) were synthesized starting from crotononitrile or methacrylonitrile and putrescine. Lithium aluminum hydride reduction of the intermediate di-Boc-nitriles resulted in corresponding di-Boc-amines, which after deprotection gave target β- and γ-MeSpd’s. To prepare α-MeSpd, the starting compound, 3-amino-1-butanol, was converted into N-Cbz-3-amino-1-butyl methanesulfonate, which alkylated putrescine to give (after deprotection of amino group) the required α-MeSpd. Novel β- and γ-MeSpd’s in combination with earlier α-MeSpd are useful tools for studying enzymology and cell biology of polyamines.
