Enantioselective Synthesis of Functionalized Fluorinated Cyclohexenones via Robinson Annulation Catalyzed by Primary−Secondary Diamines CuiHai-Feng YangYing-Quan ChaiZhuo LiPeng ZhengChang-Wu ZhuShi-Zheng ZhaoGang 2010 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.
