Estudo das condições reacionais visando a síntese do 1,2,3,4-DI-O-ISOPROPILIDENO-alfa-D-GALACTOPIRANOSE

Abstract

Carbohydrates are the most abundant macromolecules on planet earth. These can be named as: saccharides, carbohydrates, sugars or even carbohydrates. Carbohydrates have different biochemical functions when associated with nucleic acids, proteins and lipids. Many of them have the general formula: (CH 2 O) n. Carbohydrates have several applications in the technological and medicinal field. The aim of this work is to study the reaction conditions (types of inorganic salts, amount of salt and temperature) of the synthesis of 1,2: 3,4-di-O-isopropylidene-α-D-galactopyranose from D -galactose. In this sense, several tests were carried out, with the purpose of analyzing which would be the best salt employed. Thus, when subjected to the galactose protection reaction, yields of 77% and 83% of nickel sulfate and copper sulfate respectively were obtained. All synthesized compounds were characterized by different spectrometric techniques.
