Total syntheses of (-)-lycorine and (-)-2-epi-lycorine were accomplished using chiral ligand-controlled asymmetric cascade conjugate addition methodology, which enables the formation of two C-C bonds and three stereogenic centers in one pot to give synthetically useful chiral cyclohexane derivatives.
使用手性配体控制的不对称串联共轭加成方法完成了(-)-石蒜碱和(-)-2-表石蒜碱的全合成,该方法能够在一锅反应中形成两个C-C键和三个立体中心,从而得到具有合成价值的手性环己烷衍生物。
