Conformationally rigid cyclouridylic acid derivatives 2 and 3 having ethylene and propylene bridges, respectively, between the uracil 5-position and the 5'-phosphate group were synthesized. These intramolecularly cyclized compounds have predominantly the ribose pucker of C3'-endo and the g+ orientation around the C4'-C5' bond.
