Abstract: | A novel series of 1,3‐bis(2‐dihydrothiazolyl)thiaalkoxy‐p‐tert‐butylcalix[4]arenes generated by the reaction between 4,5‐dihydrothiazole‐2‐thiol and the different dibromide calix[4]aryl groups have been synthesized and structurally characterized by IR, 1H NMR, 13C NMR, and MS. From their analytical data, it was found that compounds 8, 9, and 10 had cone conformations, whereas compound 11 existed as a mixture conformation. To verify the structure of the synthetic compounds, a single‐crystal X‐ray structure of compound 8 was obtained. |
