LOWER RIM p-TERT-BUTYLCALIX[4]ARENE DERIVATIVES CONTAINING GALACTITOL PENDANTS: COMPLEXATION OF 5,11,17,23-TETRAKIS-(1,1-DIMETHYLETHYL)-25,27-DIHYDROXY -26,28-BIS-2-N-(1-DEOXY-D-GALACTITYL)-AMINOETHOXYCALIX[4]ARENE WITH Pb(II) AND F(-I)

LOWER RIM p-TERT-BUTYLCALIX[4]ARENE DERIVATIVES CONTAINING GALACTITOL PENDANTS: COMPLEXATION OF 5,11,17,23-TETRAKIS-(1,1-DIMETHYLETHYL)-25,27-DIHYDROXY -26,28-BIS-2-N-(1-DEOXY-D-GALACTITYL)-AMINOETHOXYCALIX[4]ARENE WITH Pb(II) AND F(-I)

Reductive amination of D-galactose with the bisubstituted p-tert-butylcalix[4]arylethylamine in the presence of sodium cyanoborohydride allowed the introduction of one or two galactitol residues as pendants on the lower rim. The bisubstituted secondary amine, 5,11,17,23-tetrakis-(1,1-dimethylethyl)-...
