A novel series of 2,4‐disubstituted oxazole derivatives were synthesized, screened for their anti‐tumor activity against three cell lines MCF‐7, TK‐10, and UACC‐62. Molecular docking study was carried out against epidermal growth factor receptor. A new series of 2‐phenyl‐4‐substituted oxazole derivatives were synthesized. A series of chiral α‐amino acid derivatives 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 were synthesized by coupling various l‐acylated amino acid azide 3. The synthesized compounds were tested for their in vitro antitumor activity against MCF‐7, TK‐10, and UACC‐62 cell lines. Compound 6 exhibited the strongest inhibitory activity against TK cell lines, while compound 12 showed the highest activity against MCF‐7 cell lines. Compound 14 was the most active against UACC‐62 cell lines. Furthermore, a molecular docking study of the most active compounds was carried out using epidermal growth factor receptor X‐ray 3D structure (protein data bank ID 1 M17). Docking results revealed that compound 6 showed the highest binding energy of ΔG = −78.17 Kcal/mol.
