The synthesis of a mono-galactosylated amphiphilic β-cyclodextrin, in five steps from mono-6-azido-6-deoxy-β-cyclodextrin, via coupling to a N-β-d-galactopyranosylamino-antenna is described. Both characterization by electrospray mass spectrometry and NMR show the presence of only the mono-substituted product. The Langmuir isotherms of the final product and intermediates are described.
A series of mono-hydroxy functionalised calix-[n]-arenes, and p-sulphonato-calix-[n]-arenes where n=4, 6 and 8, have been synthesised, with the pendant functions being ethoxycarbonyl methoxy group, 2-carboxy methoxy group, 2-amido methoxy group or 2-amino ethoxy group. With calix-[4]-arene and calix-[6]-arenes the compounds are obtained in good yield by treatment of the relevant p-H-calix-[n]-arene...
