In straitened circumstances: In an asymmetric version of the acid‐catalyzed acetalization of aldehydes, a novel member of the chiral confined Brønsted acid family significantly outperformed previously established catalysts, providing cyclic acetals with excellent enantioselectivity (see scheme; Ar=2‐iPr‐5‐MeC6H3).
在僵化的情况下:在醛的酸催化乙缩醛的不对称形式中,手性约束布朗斯台德酸家族的新型成员显着优于以前建立的催化剂,提供了具有出色对映选择性的环状环状缩醛(见方案; Ar = 2- i Pr- 5-MeC 6 H 3)。
