  A Flexible Route to Mannose 6-Phosphonate Functionalized Derivatives

  摘要：

  A new approach for the synthesis of a mannose 6-phosphonate isosteric analog of mannose 6-phosphate is reported. The mannosylphosphonate has been prepared in a multistep synthesis involving an homologation reaction of the methyl alpha-D-mannopyranoside followed by an Arbuzov reaction between a bromohomomannosyl derivative and the tris(trimethylsilyl)phosphite. This approach, avoiding the deprotection of dialkylphosphonate, allowed us to prepare the mannose 6-phosphonate in good yield. The described method was successfully extended to the preparation of a mannose 6-phosphonate linked to a cholesteryl moiety. This strategy affords a more general route for a wide range of functionalized mannose 6-phosphonate derivatives.
