There is described a process for the selective deprotection of hydroxy groups of nucleosides polyesters by selective hydrolysis of said polyesters in an aqueous solvent in the presence of a lipase of animal or microbial origin immobilized on a solid hydrophobic support.
Regioselective deprotection of 3′,5′-O-acylated pyrimidine nucleosides by lipase and esterase
A lipase was found to catalyze the regioselective hydrolysis at the secondaryhydroxylgroup of 2′-deoxy-3′,5′-di-O-hexanoyl pyrimidine nuclosides, whereas a protease catalyzes that at the primary hydroxylgroup.
A regioselective acylation of 2′-deoxypyrimidine nucleosides by an acid anhydride in a dry polar aprotic solvent is catalyzed by a lipase from Pseudomonas fluorescenbce.
