Enzymatic Synthesis of 5-O-acylcytarabine Vinyl Ester and Preparation of Polymeric Prodrugs of Cytarabine
We developed a facile protocol of regioselective enzymatic acylation of primary hydroxyl group of cytarabine using divinyl dicarboxylates as acyl donor. Polymerizable 5-Oacylcytarabine derivatives (2a~2d) were synthesized by immobilized lipase Novozym 435 from Candida Antarctica type B in anhydrous acetone in high yield and excellent regioselectivity. These resulting monomers were subject to the further polymerization in the second step. Homopolyrnerization in DMF with AIBN as initiator gave polymeric prodrugs (3a~3d). The obtained polymeric prodrugs were characterized with IR and NMR.
