Despite tremendous advances in enantioselective catalysis of the Diels-Alder reaction, the use of simple α,β-unsaturated esters, one of the most abundant and useful class of dienophiles, is still severely limited in scope due to their low reactivity. We report here a catalytic asymmetric Diels-Alder methodology for a large variety of α,β-unsaturated methyl esters and different dienes based on extremely
尽管在 Diels-Alder 反应的对映选择性催化方面取得了巨大进展,但简单的 α,β-不饱和酯(最丰富和最有用的亲双烯体之一)的使用范围仍然受到严重限制,因为它们的反应性低。我们在此报告了一种催化不对称 Diels-Alder 方法,用于基于极易反应的亚氨基二磷酰亚胺 (IDPi) 路易斯酸的多种 α,β-不饱和甲酯和不同的二烯。来自基于精确域的局部对自然轨道耦合簇 (DLPNO-CCSD(T)) 计算的机械见解使催化剂控制和立体化学结果合理化。
