Ring closing metathesis employing the well-known Grubbs’ ruthenium catalyst has been used as the key step in the synthesis of piperidine alkaloids, (−)-coniine and (−)-pipecoline, and the asymmetric induction has been performed by using (R)-α-methyl benzylamine as an auxiliary.
采用哌啶类生物碱,(-)-亚氨酸和(-)-胡椒碱合成的关键步骤是采用众所周知的Grubbs钌催化剂进行的闭环复分解,并且已经通过使用(R)进行了不对称诱导。-α-甲基苄胺为助剂。
