Catalytic Asymmetric Desymmetrization of meso-Diamide Derivatives Through Enantioselective N-Allylation with a Chiral π-Allyl Pd Catalyst: Improvement and Reversal of the Enantioselectivity

Autor: Kanako Yotsumoto, Osamu Kitagawa, Shinichi Matsuo, Takeo Taguchi

Publikováno v: ChemInform. 37

In the presence of the Trost ligands-Pd catalysts, N-monoallylation of bis(2,4,6-triisopropylbenzne)sulfonylamides derived from meso-1,2-diamines proceeds with good to excellent enantioselectivity (85-96% ee) to give asymmetric desymmetrization produ

[reaction: see text] N-monoallylation of meso-vicinal diamine bistrisylamides using a chiral pi-allyl-Pd catalyst proceeded in an enantioselective manner (up to 90% ee) to give desymmetrization products in good yields. The product was converted to th
