| titleOfInvention | Chemical synthesis method of O-acylcalix[4]arene |
| abstract | The invention relates to a chemical synthesis method of O-acylcalix[4]arene shown in the formula (I). The synthesis method comprises the following steps: dissolving the calixarene shown in the formula (II) in organic solvent, reacting with the acylation reagent shown in the formula (IV) at 0-150 DEG C for 0.1-10 hours under the catalysis of lithiumtrifluoromethanesulfonate shown in the formula (III), and reprocessing reaction liquid to obtain O-acylcalix[4]arene shown in the formula (I), wherein in the formula (I) and (II), R1 represents C1-C6 alkyl or hydrogen; in the formula (I) and (IV), R2 represents C1-C6 alkyl, phenyl or benzyl; and in the formula (IV), X is Cl or R2COO. The beneficial effects of the invention are as follows: the catalyst used in the reaction can be reused; the yield is high (generally over 80%); the process route is advanced, the reaction conditions are mild; and the amount of catalyst is small and the method is environmentally friendly. |
