New synthetic approach to aminoethoxy derivatives of p-(tert-butyl)calix[4]arene
摘要:
A new procedure has been proposed for the synthesis of mono- and bis(2-aminoethoxy)-p-(tertbutyl) calix[4]arenes from the corresponding mono- and bis[2-(1,3-dioxoisoindol-2-yl)ethoxy]-p-(tert-butyl)-calix[4]arenes.

reduction at 25°C and higher of the amide groups in a large number of p-tert-butylcalix[4]arene derivatives containing amide fragments with different substituents on the nitrogen atoms was accompanied by hydrogenolysis of the C-N bond with formation of the corresponding O-(2-hydroxyethyl) calixarenes and by partial cleavage of the ether bond between the calixarene framework and the substituent to give compounds
