The 13 C nmr chemical shifts have been measured for 5‐carboxymethyluracil 2 , 5‐carbo‐methoxymethyluracil 3 , their 2‐thio derivatives 4 and 5 , respectively, as well as of the three β‐D‐ribonucleosides, 5‐carboxymethyluridine 7 , 5‐carbomethoxymethyluridine 8 , and 5‐carbamoyl‐methyluridine 9 . In addition, the 13 C‐ 1 H coupling constants for 2 and 7 have, also been obtained.
