Synthesis of Monofunctionalized Calix[5]arenes

Seven OH-free and O -permethylated monofunctionalized calix[5]arenes carrying either additional methyl or tert -butyl groups are prepared following fragment condensation protocols. This strategy proves to be superior to previous approaches. Calix[5]arenes with free OH groups all adopt a cone conformation stabilized by a seam of hydrogen bonds at the lower rim. Post-condensation modifications, i.e., methylation of phenolic OH groups or functional group interconversions can also be achieved. Bulky tert -butyl groups are also found to stabilize the cone conformations of O -methylated compounds. These compounds offer versatile functional groups that make these concave molecules interesting building blocks for the synthesis of more sophisticated molecular architectures.
