Primary-secondary diamine catalysts were used to catalyze the asymmetric Robinson annulation to synthesize multiply substituted fluorinated chiral cyclohexenones with two contiguous stereogenic centers, one of which is a fluorinated quaternary chiral center, with excellent enantioselectivities and diastereoselectivities in moderate to good yields.
采用仲-仲二胺催化剂催化不对称 Robinson 环化反应,合成了具有两个连续立体中心的多取代氟化手性环己烯酮,其中一个为氟化季碳手性中心,具有优异的对映选择性和非对映选择性,中等至良好的收率。
