An efficient and reversible Temmplate- directed Photoligation of oligodeoxynucleotides (ODNs) using
-5-cyanovinyldeoxyuridine (
-CNVU) was described. When ODN containing
-CNVU at the 3' end was photoirradiated with ODN containing thymidine at the 5' end in the presence of a template ODN, an efficient photoligation was observed. The ligated ODN can be split site- selectively to regenerate parent ODN by photoirradition at the 312 nm.
