An efficient method was developed for the enantioselective reductive aldol reaction of α,β-unsaturated ketones with aldehydes in the presence of a Lewis base catalyst; conjugate reduction using a tertiary amine and trichlorosilyl triflate, followed by an aldol reaction with BINAP dioxide (BINAPO) as an organocatalyst, gave the corresponding product in high yield with high stereoselectivity.
在路易斯碱催化剂的存在下,开发了一种有效的方法,用于α,β-不饱和酮与醛的对映选择性还原醛醇缩合反应;使用叔胺和三氟甲磺酸三氯甲硅烷基还原共轭物,然后与二氧化BINAP(BINAPO)作为有机催化剂进行醛醇缩合反应,可以高产率和高立体选择性得到相应的产物。
