We are interested in developing chemically modified linear and cyclic polyglycerols and their esters that have a single polymerization degree and fine structure. Triglyceryl di-, tri-, and tetra-fatty acid esters were synthesized from common substrate as new prominent gelators. The triglyceryl esters were capable of gelling up cooking oils. A comparison of the gelation ability of structurally related compounds clarified that the introduction of alkyl chains of suitable length is required for effective gelation.

Authentic standards of cyclic polyglycerol, with well-defined structures and degrees of polymerization from 3 to 6 cyclic oligomers, have been efficiently synthesized. The intramolecular cyclization conditions gave cyclic glycerols more effectively than intermolecular coupling conditions.

A variety of authentic standards of linear, branched and cyclic oligomers of glycerol, with well-defined structures and degrees of polymerisation from 2 to 5, have been efficiently synthesised. Linear oligomers were obtained by means of a convergent approach based on regioselective opening of bis(epoxides) with solketal; branched compounds were synthesised using oxidative cleavage of the corresponding anhydrohexitols as the key step. A 6-exo-trig halocyclisation reaction involving heteroatom-tethered unsaturated alcohols permitted an efficient synthesis of the precursors of selected cyclic dimers; larger cyclic oligomers were prepared by two one-pot Williamson reactions using a ditriflate derived from diglycerol. All these methodologies permitted further scaling up.
