diphenyl H-phosphonate in pyridine furnished rapid formation of the corresponding 2′,3′-cyclic H-phosphonates 3, which upon sulfurisation and the subsequent removal of the 5′-protecting group, afforded nucleoside 2′,3′-O,O-cyclophosphorothioates 5 in high yields.
5'保护的核糖核苷与二苯基H-膦酸酯在吡啶中的反应可快速形成相应的2',3'-环H-膦酸酯3,将其硫化并随后除去5'-保护基团后,可得到核苷2',3'- O,O-环硫代磷酸酯5的收率很高。
