En route to deoxygenated N-acetyllactosamine analogues employing uridyl and galactosyl transferases

All monodeoxygenated galactoses were treated with galactokinase, and for the 2-, 3-, and 4-deoxy compounds, transformation into the corresponding galactopyranosyl phosphates could be observed. In case of the 2-deoxy derivative, further reaction via UDP-2-deoxy-d-lyxo-hexose (UDP-2-deoxygalactose), which was also obtained chemically, the multiple enzymatic system could be employed to prepare 2′-deoxy-N-acetyllactosamine.
