  Building a successful structural motif into sialylmimetics—cyclohexenephosphonate monoesters as pseudo-sialosides with promising inhibitory properties

  摘要：

  A variable synthesis of a new class of sialylmimetics which provides access to pseudo-sialosides containing the successful cyclohexene motif in the sialic acid mimicking part has been developed. The D- and L-xylo cyclohexenephosphonate scaffolds allow attachment of selected aglycons or aglycon mimetics via mixed phosphonate diester strategies and some target compounds thus synthesized displayed promising inhibitory properties when tested with parasitic or bacterial sialidases.
