Brucine-Derived Amino Alcohol Catalyzed Asymmetric Henry Reaction: An Orthogonal Enantioselectivity Approach
摘要:
A new approach to both enantioenriched Henry products is developed by use of different molecularities of metal-ligand complexes generated from Cu(I) and Zn(II) metals with readily available chiral amino alcohol 1.

With or without support? The complementary homogeneous and heterogeneouscatalystsystems have been developed for the catalytic asymmetric Friedel–Craftsalkylation of indoles with nitroalkenes, in which either of the enantiomeric products 2 could be selectively obtained under the suitable reaction conditions (i.e. with or without an added solid support; see scheme).
