Boronic esters, sugar-derived

The signal transduction in this system is thought to be derived from two separate, reversible complexations o-BBV /HPTS and o-BBV Vmonosac-charide. In the absence of sugar o-BBV and HPTS form a photo-inactive complex while in the presence of sugar o-BBV forms a boronate ester-complex. The boronate ester formation converts the dicationic viologen... [Pg.135]

The complexation of aldoses with cholesterol-derived boronic acids has been reviewed, and the changes in UV absorption and fluorescence intensity of a stilbene-type boronic acid on complexation with aldoses, especially D-fructose, have been studied with a view to their use in sugar-detection. Similar work has been carried out with diboronic acids derived from biphenyl and a -functionalized diaza-18-C-6 crown ether.A carbohydrate boronic acid derivative with liquid crystal properties referred to in Chapter 6, and further reports on boronate esters are noted in Chapter 17. [Pg.114]

Borate esters of furanoid ds-l,2-diols were shown by combined B NMR, NMR and X-ray studies to form bis(diolato)borate anions, such as 27. B NMR experiments have also been employed to investigate complexes between sugar-based bolaamphiphiles, such as the glucuronamide derivative 28, and the aromatic boronate 29. ... [Pg.328]
