This report describes the behavior of 4-hetaryliden- and 4-aryliden-5(4H)-oxazolones as dienophiles in the Diels-Alder reaction with several dienes. The application of this reaction to the synthesis of different conformationally constrained cyclicanalogues of naturalaminoacids of pharmacological interest is also described.

on a panel of 60 tumor cell lines. Additionally, molecular docking was carried out to study their binding pattern and binding affinity in the VEGFR‐2 active site using sorafenib as a reference VEGFR‐2inhibitor. Based on the molecular docking results, compounds 5a, 5b, 6, 7, 14b, 18b, and 18c were selected to be evaluated for their VEGFR‐2 inhibitory activity. Compound 18b exhibited a broad‐spectrum
