Abstract:

2-Aminobenzyl alcohol and its derivatives are a kind of important bifunctional compounds, and has found wide application in organic chemistry and drug synthesis. An efficient and simple method for synthesis of 2-(arylaminoethylamino)benzyl alcohols was described and the fungicidal activities of the target compounds were evaluated in this paper. N-alkylation of 2-aminobenzyl alcohol with bromoacetyl aryl amines produced 2-[(2-hydroxymethylphenyl)amino] acetyl aryl amines 3a~3i, which were reduced by LiAlH4 giving a series of novel 2-(arylaminoethylamino)benzyl alcohols 5a~5i in 76%~95% yields. All the structures of the target compounds were characterized by the infrared spectroscopy(IR), proton nuclear magnetic resonance spectroscopy(1H NMR), 13C NMR and elemental analysis. Most of compounds show moderate to good fungicidal activities under the testing concentration. Compound 5e shows 73% activity of against Phytophythora capsici.

Key words: (arylaminoethylamino)benzyl alcohol, alkylation, synthesis, fungicidal activity
