  名称：

  Synthesis of an ether-linked alkyl 5a-carba-β-d-glucoside, a 5a-carba-β-d-galactoside, a 2-acetamido-2-deoxy-5a-carba-β-d-glucoside, and an alkyl 5a′-carba-β-lactoside

  摘要：

  For the purpose of providing biologically stable building blocks for the biocombinatorial synthesis using a living cell, some ether-linked alkyl 5a-carba-beta-D-glycoside primers were prepared. The key step of the synthesis was coupling of 1-bromo-n-alkanes with the 1-OH unprotected derivatives of 5a-carba-sugar analogues of D-glucose, D-galactose, and 2-acetamido-2-deoxy-D-glucose (N-acetyl-D-glucosamine). in DMF in the presence of sodium hydride. Alternatively, alkyl carba-lactoside was synthesized by incorporation of a 5a-carba-beta-D-galactose residue into the 4-position of dodecyl beta-D-glueopyranoside, A strong and specific inhibition of beta-galactosidase (K-i 0.67 muM bovine liver) was found for dodecyl 5a-carba-beta-D-galactopyranoside.
