Abstract In this article, five kinds of soybean oil-based polyols (polyol-E, polyol-P, polyol-I, polyol-B, and polyol-M) were prepared by ring-opening the epoxy groups in epoxidized oil (ESO) with ethyl alcohol, 1-pentanol, isoamyl p -tert-butylphenol, 4-methoxyphenol presence tetrafluoroboric acid as catalyst. The SOPs characterized FTIR, 1 H NMR, GPC, viscosity, hydroxyl numbers. Compared ESO...

Valorization of industrial low-value side-streams are great interest, contributing to boosts in the circular economy. In this context, lignin pulp and paper industry were oxypropylated produce biobased polyols tested synthesis rigid polyurethane (RPU) foams. E. globulus lignins, namely a isolated from an Kraft black liquor depolymerized lignins obtained as by-products oxidation process, used. R...

Modification of the dipeptide of phenylalanine, FF, with a boronic acid (BA) functionality imparts unique aqueous self-assembly behavior that responds to multiple stimuli. Changes in pH and ionic strength are used to trigger hydrogelation via the formation of nanoribbon networks. Furthermore, we show for the first time that the binding of polyols to the BA functionality can modulate a peptide b...

An efficient and divergent synthesis of polyol subunits utilizing a phosphate tether-mediated, one-pot, sequential RCM/CM/reduction process is reported. A modular, 3-component coupling strategy has been developed, in which, simple "order of addition" of a pair of olefinic-alcohol components to a pseudo-C 2-symmetric phosphoryl chloride, coupled with the RCM/CM/reduction protocol, yields five po...

[reaction: see text] A practical and environmentally friendly organocatalytic strategy designed to mimic the DHAP aldolases has been developed and shown to be effective in the preparation of carbohydrates and aminosugars. (S)-Proline and (S)-2-pyrrolidine-tetrazole catalyzed the aldol reaction between dihydroxy acetone variants such as 1,3-dioxan-5-one and 2,2-dimethyl-1,3-dioxan-5-one with ald...
