title: Potential sialyltransferase inhibitors based on neuraminyl substitution by hetaryl rings.
abstract: Replacement of the neuraminyl residue by a wide range of aryl rings in transition-state analogs of CMP-Neu5Ac led to readily accessible and potent inhibitors of alpha-(2-->6)- and alpha-(2-->3)-sialyltransferases. The synthesis of a series of potential sialyltransferase inhibitors in which the neuraminyl residue is replaced by hetaryl methylphosphonate residues (thiazole, benzothiazole, benzoxazole, benzothiophene and thiophene) is described in this paper.
