The odd couple: The synthesis of 20,20‐difluorocatharanthine starting from naturally occurring catharanthine is reported. The fluorinated catharanthine analogue was investigated as a potential precursor to dimeric Vinca alkaloids of the vinflunine family. However, the biomimetic coupling of difluorocatharanthine with vindoline led to unexpected products, the formation of which was rationalized (see
奇怪的一对:据报道从天然存在的catharanthine开始合成20,20-difluorocatharanthine。研究了氟化的长春花碱类似物作为长春氟宁家族二聚长春花生物碱的潜在前体。然而,二氟金刚烷胺与长春花碱的仿生偶联导致了意想不到的产物,其形成是合理的(参见方案)。
