The nucleoside antibiotic ascamycin [2-chloro-5'-g-[I+(k-alanyljsulfamoyl) adenosine (l)] has been synthesized by an improved procedure involving the direct condensation of 2-chloro-2',3'-~-isopropylidene-5'-~-sulfamoyladenosine (3) with Bock-Ala-O% in DMF and in the presence of DBU. followed by rem
## Abstract A concise route to nucleoside β‐hydroxyphosphonate analogues is described. The use of a nucleoside β‐ketophosphonate as the key intermediate allowed both the (__R__) and (__S__) isomers of β‐hydroxyphosphonate analogues in the pyrimidine series to be accessed. Such derivatives may be co
