The invention belongs to the technical field of pharmaceutical chemistry, and discloses an amide aromatic phenol antibacterial peptide analogue with drug-resistance bacteria resistant activity and without obvious toxicity and a preparation method thereof. The target product is obtained by 3-4 reaction steps, and the main structure of the product is shown as follows. In-vitro antibacterial activityexperiments prove that most of the series of compounds have excellent activity on Gram-positive staphylococcus aureus and enterococcus faecalis, Gram-negative Escherichia coli and stenotrophomonas maltophilia, and the compounds have excellent broad spectrum antibacterial activity; moreover, in-vitro red cell hemolytic data is low in toxicity and has excellent selectivity. One part of the compounds also have excellent antibacterial activity on 'superbacteria' comprising drug-resistant methicillin staphylococcus aureus (MRSA), clinical strains producing enzymes NDM-1 and KPC-2 and the like. Therefore, the series of com
