Disclosed are methods of purifying glycopeptides that are substituted with one or more substituents each comprising one or more phosphono groups that are useful as antibacterial agents. The methods include contacting a solution of the glycopeptide derivatives with a polystyrene-containing resin, eluting the resin with an aqueous solution, and isolating the purified glycopeptide derivative.
Disclosed are derivatives of glycopeptide antibiotic compounds having at least one substituent of the formula:
—R
a
—Y—R
b
—(Z)
x
where R
a
, R
b
, Y, Z and x are as defined, and having a group W at the glucose C-6 position, where W is as defined; and pharmaceutical compositions containing such glycopeptide derivatives. The disclosed glycopeptide derivatives are useful as antibacterial agents.

Disclosed are processes for preparing glycopeptide phosphonate derivatives having an amino-containing side chain. Several of the process steps are conducted in a single reaction vessel without isolation of intermediate reaction products, thereby generating less waste and improving the overall efficiency and yield of the process.
