Nanoscaled inclusion complexes of β-cyclodextrin with binuclear compounds based on diols containing fragments of selected aromatic monocarboxylic acids
摘要:
Stable nanoscaled mono- and dimeric inclusion complexes of beta-cyclodextrin with hosts based on symmetric diols of various length containing fragments of benzoic, nicotinic, or isonicotinic acid were synthesized.

An efficient methodology for the synthesis of symmetrical methylene diesters was developed through direct reaction of various aromatic carboxylates with 1,n-dihaloalkanes under solvent-free conditions. This strategy offers a high product yield, facile work-up and purification, and an environmentally friendly approach to obtain long-chain methylene carboxylate scaffolds with increased diversity.
