摘要

Abstract The incorporation of a specific cleavage site into an oligodeoxynucleotide can be achieved by utilizing the four 5′-S-(4, 4′-dimethoxytrityl)-2′-deoxy-5′-thionucleoside 3′-(2-cyanoethyl diisopropylphosphoramidites) 5 and 15a–c (Fig. 1). Based on the silver ion assisted cleavage of P [BOND] S and C [BOND] S bonds, we synthesized oligodeoxynucleotides with an achiral 5′-phosphorothioate linkage 3′–O–P–S–5′ by ...
