will insert a cleavage site in an oligodeoxynucleotide, which can be used for a selective and quantitative cleavage. For that reason we synthesized the four 5′-S-(4,4′-dimethoxytrityl)-mercapto-2′-deoxynucleotide-3′-O-(2-cyanoethoxydiisopropylamino)-phosphites ( 5a–d ). The cleavage of P-S and C-S bonds is described (Mag, M.; Lücking, S.; Engels, J.W. Synthesis and selective cleavage of an oligodeoxy-nucleotide
摘要我们将在寡聚脱氧核苷酸中插入一个切割位点,可用于选择性和定量切割。因此,我们合成了四个5'-S-(4,4'-二甲氧基三苯甲基)-巯基-2'-脱氧核苷酸-3'-O-(2-氰基乙氧基二异丙基氨基)-亚磷酸酯(5a–d)。描述了PS和CS键的裂解(Mag,M .;Lücking,S .; Engels,JW合成和选择性裂解含有桥连的核苷酸间5'-硫代磷酸酯键的低聚脱氧核苷酸Nucleic Acids Res。1991,19(7 ),1437–1441;万豪酒店,JH; Mottahedeh,M .;里斯(Reese),CB 9-(4-甲氧基苯基)氧杂蒽-9-硫醇:一种有用的硫醇试剂。Tetrahedron Lett。1990,31(51), 7485–7488; Divakar,KJ; Mottoh,A。; Reese,CB; Shanghvi,YS合成嘧啶核糖苷2'硫代类似物的方法。珀金(
