Asymmetric Inter- and Intramolecular Cyclopropanation Reactions Catalyzed by a Reusable Macroporous-Polymer-Supported Chiral Ruthenium(II)/Phenyloxazoline Complex
Along came poly: A novel macroporous polymer‐supported chiral RuII/pheox catalyst (1, see SEM image) afforded excellent reactivity and enantioselectivity in inter‐ and intramolecular cyclopropanation reactions with a broad range of substrates. The catalyst showed no leaching and could be reused up to 11 times, even after storage.
随之而来的是聚:一种新型的大孔聚合物负载的手性Ru II / pheox催化剂(1,参见SEM图片)在与多种底物的分子间和分子内环丙烷化反应中具有出色的反应性和对映选择性。该催化剂没有浸出,即使在储存后也可以重复使用多达11次。
