The enantiopure non-natural amino acids1 have been synthesized by insitu generation of iminium and iminium triflates from lactams using triflic anhydride in pyridine buffered media. These molecules with remote chiral centers may be useful in synthesis of natural product particularly Kopsia derived alkaloids.
对映纯非天然氨基酸1是通过在吡啶缓冲的介质中使用三氟甲磺酸酐从内酰胺原位生成亚胺基亚胺基和亚胺基亚胺基三氟甲磺酸盐而合成的。这些具有较远手性中心的分子可用于合成天然产物,尤其是从Kopsia衍生的生物碱。
