In carbohydrate chemistry carbohydrate acetalisation is an organic reaction and a very effective means of providing a protecting group . The example below depicts the acetalisation reaction of D ribose 1 . With acetone or 2,2 Dimethoxypropane 2,2 dimethoxypropane as the acetalisation reagent the reaction is under thermodynamic reaction control and results in the pentose 2 . The latter reagent in itself is an acetal and therefore the reaction is actually a cross acetalisation . image Carbohydrateacetalisation.gif center Kinetic reaction control results from 2 methoxypropene as the reagent. D ribose in itself is a hemiacetal and in equilibrium with the pyranose 3 . In aqueous solution ribose is 75 pyranose and 25 furanose and a different acetal 4 is formed.
