Alkylaminophenols are synthetic derivatives well known for their anticancer activity. In this work, we report the antimicrobial and antioxidant activity of such compounds. A series (4,5,6) alkylaminophenol compounds were prepared with very high yields by Petasis reaction. Synthesized characterized 1 H-NMR 13 C-NMR. The obtained tested against Gram-positive Gram-negative bacteria. compound 4 showed at a concentration 10 mg/mL, while 6 on S. aureus. Phenolic have attracted attention due to...

In this study, a new alkylaminophenol compound was synthesized and characterized by spectroscopic techniques (FT-IR, NMR, UV). The optimized molecular geometry the vibrational wavenumbers were calculated using density functional theory (DFT) B3LYP/WB97XD HF methods with 6-311++ G([Formula: see text], [Formula: text]) basis set. Thus, theoretical data compared within themselves before comparing experimental data. detailed interpretation of spectra has been carried out VEDA program. 1 H-NMR...
