Synthesis of calixarene–cyclodextrin coupling products
摘要:
The coupling of two or four mono-6-amino beta-cyclodextrin (amino-CD) units, (unprotected or permethylated hydroxyls), to diisopropoxycalix[4]arene crown-6 (CAL) was realised using the N,N'-succinyldiamide linker. The resulting molecules in two series were characterised with the help of mass and NMR spectroscopies. The yields of all coupling products were improved for permethylated sugar series compared to the hydroxylated CD series or to our previous studies. The two beta-cyclodextrin (beta-CD) residues coupled to disubstituted CAL were orientated from the same side of the crown ether. (c) 2006 Elsevier Ltd. All rights reserved.
