In a first aspect, the present invention relates to a method for the preparation of alkynylpiperidine and alkynylpiperidine derivatives. In particular, a method is provided for preparing alkynylpiperidine derivatives starting from epoxide compounds. Further, the alkynylpiperidine derivatives according to the present inventions are substituted trans-3- 4-alkynylpiperidine derivatives. In another aspect, triazolylpiperidine compounds and methods for said preparation are provided. In particular, the triazolylpiperidine compounds according to the present invention are obtained by reacting an alkynylpiperidine derivatives with an organic azid, preferably, in the presence of a Cu (I) or Ru catalyst. In a preferred embodiment, 1,4-disubstituted or 1,5-disubstituted 1,2,3-triazolylpiperidine compounds are provided.
第一方面,本发明涉及一种制备炔基哌啶和炔基哌啶衍生物的方法。特别是提供了一种从环氧化合物开始制备炔基哌啶衍生物的方法。此外,根据本发明的炔基哌啶衍生物是取代的反式-3- 4-炔基哌啶衍生物。另一方面,本发明提供了三唑基哌啶化合物及其制备方法。特别是,根据本发明的三唑基哌啶化合物是通过烷基哌啶衍生物与有机叠氮反应得到的,最好是在 Cu (I) 或 Ru 催化剂存在下反应。在一个优选的实施方案中,提供了 1,4-二取代或 1,5-二取代的 1,2,3-三唑基哌啶化合物。
