The synergy of multicomponent reactions (MCRs) and metathesis chemistry is applied for the synthesis of bio‐based functional isosorbide polymers (i.e., polyesters) decorated with α‐acyloxy amide motif. The chemical structure of the polyesters that are not accessible by any other conventional methodologies is characterized in‐depth via nuclear magnetic resonance, size‐exclusion chromatography, and attenuated total reflectance infrared spectroscopy. It is also observed that the "biomass‐derived" carbon % of the polymers varied between 66.2 and 76.9. Moreover, the thermal properties of the novel isosorbide‐based polymers are investigated via thermogravimetric analysis and differential scanning calorimetry, revealing that the polymers are in the amorphous state, identified by the glass transition temperature (Tg) values below the human body temperature. The mechanical properties and the biocompatibility of the functional novel polyester derivative with the highest "biomass‐derived" carbon % are evaluated via dynamic mechanical analysis and cytotoxicity test. The exemplary polymer is biocompatible with chondrocyte cells in the conditions used in the tests. In summary, the complementary nature of isosorbide derivatives with MCRs and metathesis chemistry is utilized to illustrate the potential utility of isosorbide as a building block for polymers with prospective biomedical application (namely, as novel cartilage materials).
