在 rt–100 °C 的 K 2 CO 3作用下,杂芳基卤化物 (Cl, Br) 和硫醇之间的亲核芳香取代 (S N Ar) 在 DMAc 中顺利进行。对于大多数缺电子杂芳烃,反应的发生无需引入额外的吸电子基团。对于富电子杂芳烃,需要额外的吸电子基团(例如简单的酯基、酮基、氰基和硝基)以确保反应完成。杂芳基卤化物的反应性趋势高度依赖于杂芳烃的电子性质和卤素的方向。除了硫醇之外,一些官能化的硫脲和硫代酰胺也与这些条件相容,以良好的产率提供相应的杂芳基硫醚。

The present invention is directed to a method for the synthesis of a bi-functional complex comprising a molecule part and an identifier oligonucleotide part identifying the molecule part. A part of the synthesis method according to the present invention is preferably conducted in one or more organic solvents when a nascent bi-functional complex comprising an optionally protected tag or oligonucleotide identifier is linked to a solid support, and another part of the synthesis method is preferably conducted under conditions suitable for enzymatic addition of an oligonucleotide tag to a nascent bi-functional complex in solution.
