Calix[4]arenes are an exciting class of multifunctional compounds. Their ability to bind small molecules and ions actively makes them useful tools for many applications. While looking for a suitable chelating agent, a particular modification of the calix[4]arene led to an unexpected side reaction. In this work, we will describe the selective formation of the observed acyloxyacetate derivatives. The
