In an article, published in an article, once mentioned the application of 21436-03-3, Name is (1S,2S)-Cyclohexane-1,2-diamine,molecular formula is C6H14N2, is a conventional compound. this article was the specific content is as follows.Formula: C6H14N2
A highly diastereo-and enantioselective copper(I)-catalyzed henry reaction using a bis(sulfonamide)-diamine ligand
A series of bis(sulfonamide)-diamine (BSDA) ligands were synthesized from commercially available chiral alpha-amino alcohols and diamines. The chiral BSDA ligand 3a, coordinated with Cu(I), catalyzes the enantioselective Henry reaction with excellent enantioselectivity (up to 99%). Moreover, with the assistance of pyridine, a CuBr-3a system promotes the diastereoselective Henry reaction with various aldehyde substrates and gives the corresponding syn-selective adduct with up to a 99% yield and 32.3:1 syn/anti selectivity. The enantiomeric excess of the syn adduct was 97%.
