## Abstract The preparation of functionalized resorcinarenes is described. Thus, 2‐nitroresorcinol (= 2‐nitrobenzene‐1,2‐diol), 2‐acetylresorcinol (= 1‐(2,6‐dihydroxyphenyl)ethanone), and 2,6‐dihydroxybenzoic acid were treated with formaldehyde in alkaline medium to give the corresponding resorcina
The acid-catalyzed (with HCl) condensation reactions of resorcinol ( ) with 1-naphthaldehyde (2) and isobutyraldehyde (3) furnished the tetrameric macrocyclic compounds 4 and 6. Detailed NMR-investigations of the acetylated tetrameric species 5 surprisingly support a structure not in agreement with
