| Abstract: | Novel unsymmetrical di(thienyl)maleic acid anhydride, including coumarin moiety, has been designed and synthesized. Its photochromism study and fatigue resistance estimation are reported. Microwave‐assisted procedure has been successfully used for synthesis of 3‐(5‐methylthiophen‐2‐yl)coumarins. |
