摘要:从 N,N-二甲胺和 D2O 开始,合成了 Ribociclib 的氚代片段,用作质谱内标.此外,还对酰胺化反应过程中 D0(未标记物质)的形成进行了系统研究,从而确定了一种偶联试剂 Hatu(o-(7-氮杂苯并三唑-1-基)-N,N,N',N'-四甲基脲六氟磷酸盐)是主要原因.最后,我们设计了一条替代路线,使用 Edci/hobt 作为偶联试剂,生成所需的无 D0 残留的氚代化合物.

摘要:The present invention generally relates to a process for the synthesis of selectively alkylated cyclodextrins. More particularly, the present invention relates to a process of cyclodextrin alkylation in a selective manner yielding hexakis(2,6-di-O-alkyl)-alpha-cyclodextrin, heptakis(2,6-di-O-alkyl)-beta-cyclodextrin and octakis(2,6-di-O-alkyl)-gamma-cyclodextrin.
