摘要:从六个工业上可获得的氟化吡啶开始,开发了一种方便的途径来获取所有三个四氟吡啶(2-4),所有六个三氟吡啶(5-10)和五个非商业性二氟吡啶(11-14和16).用于从多氟吡啶中选择性除去氟的方法是通过金属或复合氢化物进行还原,并用肼进行位点选择性置换,然后进行脱氢-脱重氮或脱氢氯化-脱重氮.为了引入额外的氟原子,在进行氯/氟置换过程之前,将合适的前体金属化和氯化.

摘要: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.
