The article was written by Yildirim, Ayhan. The article contains the following contents:
The present work was undertaken to ascertain whether IL-metal salt catalyzed isopropylidenation of D-fructose yield desired acetonides. For the first time, an imidazole based ionic liquid compound accompanied with strontium chloride has been identified as a suitable dual catalyst system for the chemoselective O-isopropylidenation of D-fructose with acetone. In the present protocol, mainly the kinetically controlled less stable cyclic ketal 1,2;4,5-di-O-isopropylidene-β-D-fructopyranose is formed as an initial product with satisfactory yield and without isomerization to the thermodynamically more stable cyclic ketal 2,3;4,5-di-O-isopropylidene-β-D-fructopyranose. Therefore, this protocol is more advantageous compared to other mineral acid catalyzed protocols that require more sensitive reaction conditions.
