  First Regioselective Enzymatic Alkoxycarbonylation of Primary Amines. Synthesis of Novel 5‘- and 3‘-Carbamates of Pyrimidine 3‘,5‘-Diaminonucleoside Derivatives Including BVDU Analogues

  摘要：

  The first regioselective enzymatic alkoxycarbonylation of primary amino groups has been achieved in pyrimidine 3',5'-diaminonucleoside derivatives. Thus, Candida antarctica lipase B (CAL-B) catalyzed this reaction with nonactivated homocarbonates allowing the selective synthesis of several N-5' carbamates, including (E)-5-(2-bromovinyl)-2'-deoxyuridine (BVDU) analogues, with moderate-high yields, whereas immobilized Pseudomonas cepacia lipase (PSL-C) afforded mixtures of alkoxycarbonylated regioisomers. To obtain N-3' carbamates selectively, a short and efficient chemoenzymatic route was used employing some of the N-5'-protected derivatives previously synthesized.
