Abstract: The chemistry of crown ethers and cyclodextrins has developed in a remarkable fashion during the past 25 years largely because of the ready accessibility of these compounds — through the talents of the synthetic chemist in the first instance and Nature in the second. Ready accessibility also accounts for the increasing attention that the macrocycles named calixarenes [1] have received during the past decade. The first part of this chapter deals with the methods that have been devised for constructing the calixarenes in a single step reaction from phenols and formaldehyde. This is followed by a discussion of methods for introducing functional groups onto the ‘upper’ and ‘lower’ rims of the calix, and the chapter concludes with a brief commentary on the physical properties of the calixarenes.
