Just relax: A one-pot, three-enzyme chemoenzymatic synthetic approach is highly efficient for obtaining complex sialosides that contain diverse naturally occurring sialic acid modifications. α-2,6-Linked sialosides containing twelve naturally occurring sialic acid forms and seven non-natural sialic acid forms have been obtained.
