  Synthesis and ‘click’ cycloaddition reactions of tetramethoxy- and tetrapropoxy-2-(ω-azidoalkyl)calix[4]arenes

  摘要：

  2-(omega-Chloroalkyl)tetramethoxycalix[4]arenes are converted to 2-(omega-azidoalkyl)tetramethoxy- and cone-2-(omega-azidoalkyl)tetrapropoxycalix[4]arenes, the former by substitution and the latter by demethylation to 2-(omega-chloroalkyl)tetrahydroxycalix[4]arenes, which are O-propylated before substitution of azide for chloride. The azide-terminated calixarenes undergo Cu(I)-catalyzed 1,3-cycloaddition to terminal alkynes to give 1,4-disubstituted 1,2,3-triazoles, demonstrating the potential to couple calixarenes from a tether at the 2-position (methylene bridge) to substrates that bear a terminal alkyne group. The cone conformation of cone-2-(4-chlorobutyl)tetrapropoxycalix[4]arene has been confirmed by X-ray diffraction. (C) 2011 Elsevier Ltd. All rights reserved.
