An efficient and high yield protocol for the synthesis and separation of 3‘- and/or 5‘-protected α-2‘-deoxynucleosides has been developed through regioselective acylation/deacylation processes catalyzed by enzymes. Pseudomonas cepacia lipase (PSL-C) was found to be highly chemo- and regioselective toward the 3‘-position of the β-2‘-deoxynucleoside derivatives, whereas PSL-C displayed opposite selectivity
