A simple organocatalytic Michael-aldol-dehydration domino approach to chiral 3,5-diaryl-cyclohexenones from acetone and α,β-unsaturated ketones was developed for the first time using a simple chiral primary amine as a catalyst. Moderate to good yields (up to 85%) and excellent enantioselectivities (88–98% ee) were obtained.
首次使用简单的手性伯胺作为催化剂,开发了一种简单的有机催化迈克尔-羟醛脱水多米诺方法,该方法用于从丙酮和α,β-不饱和酮中手性化3,5-二芳基-环己烯酮。获得了中等至良好的收率(高达85%)和出色的对映选择性(88-98%ee)。
