Lower-rim mono- and diacylated calix[4]arenes [acyl = C6H5CO, 3,5-(NO2)(2)C6H3CO] undergo selective adamantylation with 3-Y-1-adamantanols (Y = H, i-Pr, 4-MeC6H4) in trifluoroacetic acid at the free phenolic fragments of the macroring. The reaction provides a convenient preparative route to di-, tri-, and tetraadamantylated calix[4]arenes.
