Yu, Chang-Bin published the artcilePalladium-Catalyzed Asymmetric Hydrogenolysis of N-Sulfonyl Aminoalcohols via Achiral Enesulfonamide Intermediates, Category: dioxole, the publication is Angewandte Chemie, International Edition (2013), 52(50), 13365-13368, database is CAplus and MEDLINE.
A stereoconvergent palladium-catalyzed formal asym. hydrogenolysis of N-sulfonyl aminoalcs. was successfully developed with a chiral palladium complex as the catalyst in the presence of trifluoroacetic acid to provide direct and facile access to chiral 2,3-dihydro-1H-inden-2-amine derivatives with two contiguous stereogenic centers with up to 94% ee.
