[摘要]：Derivatives, and Condensed Benzenoid Compounds) Section Starting from the resorcin[4]arene tetrabromide I (R = Br, cone conformation) a no. of amino derivs. I (R = NH2, NHBn, 4-picolylamino, NHMePh) were prepd. Preliminary investigations, including UV, NMR, and MS anal., of mixts. of the resorcinarene and its potential guests, such as metal cations or amino acids, evidenced promising new properties, depending on the nature of the substituents. Notably, treatment of I (R = Br) with pyridine gave readily the corresponding pyridinium salt, capable of interacting with Ga(III) salts in aq. soln. The same results were obtained starting from I (R = Br, 1,2-alternate conformation) for two of the above reactions, giving I (R = NH2, pyridinio). |
