Intramolecular bridging of calix[4]arene dialdoximes
Original language description
A novel method for the intramolecular bridging of calix[4]arenes, based on the reductive coupling of dial-doximes, is described. Reaction of the distal dialdoxime, immobilized in the cone conformation, using Zn/TiCl4 afforded a calixarene with a 1,2-diaminoethane bridge and possessing mesa stereochemistry. The reaction was found to be very sensitive to the conformation of the starting calixarene as evident by the absence of similar products in the 1,3-alternate conformation. meso-Diamino-bridged calixarenes represent unique synthetic intermediates with possible application in the design of new receptors.
