Application of 21436-03-3, An article , which mentions 21436-03-3, molecular formula is C6H14N2. The compound – (1S,2S)-Cyclohexane-1,2-diamine played an important role in people’s production and life.
Chiral salen-metal complexes have been tested as catalysts for the C-alkylation of Schiff’s bases of alanine and glycine esters with alkyl bromides under phase-transfer conditions (solid sodium hydroxide, toluene, ambient temperature, 1-10 mol% of the catalyst). The best catalyst, which was derived from a Cu(II) complex of (1R, 2R or 1S,2S)-[N,N?-bis(2?-hydroxybenzylidene)]-1,2-diaminocyclohexane, gave alpha-amino and alpha-methyl-alpha-amino acids with enantiomeric excesses of 70-96%.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 21436-03-3, help many people in the next few years., Application of 21436-03-3
