The synthesis of 6′S-Me-2′-O,4′-C-ethylene-bridged 5-methyluridine (6′S-Me-ENA-T) was achieved using visible light-mediated stereoselective radical cyclization as a key step. This is the first example of a method for constructing a 2′,4′-bridged structure

Oligonucleotides containing 4′-carboxy-, 4′-methoxycarbonyl-, 4′-carbamoyl-, and 4′-methylcarbamoyl-thymidines, and their 2′-methoxy, 2′-amino or 2′-acetamido analogs were prepared. Their duplex-forming ability with DNA and RNA complements was evaluated by UV melting experiments. Interestingly, 4′-carboxythymidine existing in the S-type sugar conformation was found to lead to an increase in the stability of the duplex formed with RNA complements compared to natural thymidine.
