An oxidative Pd-catalyzed intra-intermolecular dioxygenation of (aza-)alkenols has been reported, with total regioselectivity. To study the stereoselectivity, different chiral ligands as well as different hypervalent-iodine compounds have been compared. In particular, by using a C-6 modified pyridinyl-oxazoline (Pyox) ligand and hypervalent iodine bearing an aromatic ring, an excellent enantio- and
据报道,氧化钯催化的(氮杂)烯醇分子间双氧化反应具有完全区域选择性。为了研究立体选择性,比较了不同的手性配体以及不同的高价碘化合物。特别是,通过使用C-6修饰的吡啶基恶唑啉(Pyox)配体和带有芳香环的高价碘,实现了优异的对映选择性和非对映选择性。
