  An organocatalytic asymmetric α-sulfenylation of 2-substituted indolin-3-ones with N-(alkylthio or arylthio)succinimides has been developed for the first time using Cinchona-derived squaramide as the catalyst. Various chiral 2,2-disubstituted indole-3-ones with S- and N-containing heteroquaternary carbon stereocenters were obtained with up to 98% yield and 99% ee.

  The invention provides a novel method for producing an oligonucleotide using a nucleoside or oligonucleotide that is easy to isolate and has high storage stability. The oligonucleotide production method includes a step of subjecting a nucleoside or oligonucleotide having a pseudo solid phase-protecting group in at least one location selected from the group consisting of 2'-position, 3'-position, 5'-position and a nucleobase moiety and having a 5'-hydroxyl group or a 3'-hydroxyl group, to H-phosphonation to convert the 5'-hydroxyl group or the 3'-hydroxyl group into an H-phosphonated form.

  本发明提供了一种使用核苷或寡核苷酸生产寡核苷酸的新方法，该方法易于分离且具有较高的储存稳定性。该寡核苷酸生产方法包括以下步骤：将至少在选自 2'-位、3'-位、5'-位和核碱基分子组成的组中的一个位置上具有伪固相保护基团且具有 5'-羟基或 3'-羟基的核苷或寡核苷酸进行 H-膦化，以将 5'-羟基或 3'-羟基转化为 H-膦化形式。
