A new sulfurizing reagent is reported for the automated synthesis of phosphothioate analogues of oligonucloetides via the phosphoramidite method. Bis(O,diisopropoxy phosphinothioyl) disulfide (S-Tetra, 1) is relatively inexpensive to prepare, easy to handle, and efficiently sulfurizes internucleotide phosphites, thus allowing the practical synthesis of oligo(nucleoside phosphorothioate)s with exceptionally
据报道,一种新的硫化试剂可通过亚磷酰胺方法自动合成寡核苷酸的硫代磷酸酯类似物。双(O,二异丙氧基膦硫基硫醚基)二硫化物(S-Tetra,1)相对便宜,制备,易于处理并有效地硫化核苷酸间亚磷酸酯,因此可以实际合成具有极高硫含量的寡聚(核苷硫代磷酸酯)。
