Three derivatives of dehydroabietylamine were synthesized from dehydroabietylamine through trifluoro-acetyltion,nitration and hydrolysis.Two of them were first reported as new compounds.The compounds were characterized by FT-IR,1H NMR,EI-MS,elemental analyses and HRMS.Their bactericidal activities were investigated,and the results indicated that 12-nitro-dehydroabietylamine and 12,14-dinitro-dehydroabietylamine had strong bactericidal activity against E.coli,Staphylococcus aureus,Pseudomonas fluorescens.
Positive electrospray ionization tandem mass spectrometry was applied to study four newly synthesized(12-aminodehydroabietylamine)acetamide-substituted salicylidene Schiff bases(ADASSSB).The results showed that the MSn characteristics of ADASSSB can be used for their qualitative and quantitative analysis.
