摘要： A process of manufacturing oligonucleotides includes a 5′-deblocking step in which the 5-blocking group is removed with dichloroacetic acid that is essentially free of chloral. The process is useful for making oligonucleotides that are substantially free of chloral adducts.

摘要： Synthetic processes are provided wherein oligomeric compounds are prepared having phosphodiester, phosphorothioate, phosphorodithioate, or other covalent linkages. The oligomers have substantially reduced exocyclic adducts deriving from acrylonitrile or related contaminants.
摘要翻译： 提供合成方法，其中制备具有磷酸二酯，硫代磷酸酯，二硫代磷酸酯或其它共价键的低聚化合物。 低聚物具有显着减少的衍生自丙烯腈或相关污染物的环加成物。
