Calix[4]resorcinarenes are polyhydroxylated macrocyclic compounds with four units of resorcinol. These compounds can be derivatized through modifications at the upper rim, allowing reactivity with secondary amines to produce Mannich base derivatives via Mannich-type aminomethylation reactions. In th...

description Calix[4]resorcinarenes are polyhydroxylated macrocyclic compounds with four units of resorcinol. These compounds can be derivatized through modifications at the upper rim, allowing reactivity with secondary amines to produce Mannich base derivatives via Mannich-type aminomethylation reactions. In this paper, we report the reaction of <i>C</i>-tetra(propyl)calix[4]resorcinarene with piperidine in acetonitrile. The aminomethylated compound <i>C</i>-2,8,14,20-tetra(propyl)-5,11,17,23-tetrakis(N–(piperidine)methyl)calix[4]resorcinarene was obtained with a 52% yield, with an exact mass of 1044.6994 u and a mass error of 7.6 ppm. The reaction progress and product formation were monitored by RP-HPLC, and the compound was characterized using LC ESI-TOF/MS, one- and two-dimensional <sup>1</sup>H and <sup>13</sup>C NMR, and FTIR spectroscopy. Chromatographic and spectroscopy data are presented and discussed.
