摘要:
The present invention relates to an improvement in the process for preparing a calixarene derivative in which the rotation of its benzene units are hindered and which comprises replacing all or a part of the hydrogen atoms of the hydroxyl groups of a calixarene derivative represented by the general formula: ##STR1## and is characterized by conducting the reaction in the presence of an alkaline earth metal. According to the present invention, an asymmetric calixarene derivative having a "cone" conformation can be selectively prepared by virtue of the template effect of the metal.
