I found the field of Chemistry very interesting. Saw the article Synthesis of chiral polyurethanes of cinchona alkaloids for the enantioselective synthesis in asymmetric catalysis published in 2019. Recommanded Product: 90-44-8, Reprint Addresses Itsuno, S (corresponding author), Toyohashi Univ Technol, Dept Environm & Life Sci, Toyohashi, Aichi 4418580, Japan.. The CAS is 90-44-8. Through research, I have a further understanding and discovery of Anthrone
Chiral polyurethanes of cinchona alkaloid were synthesized via repetitive Mizoroki-Heck (MH) coupling reaction. The Pd-catalyzed polycondensation of cinchona urethane dimers and aromatic diiodides afforded the chiral polyurethanes. The chiral polyurethane bearing free OH group at the C6′ position of the quinoline ring in the cinchona alkaloid unit showed high catalytic activities and excellent enantioselectivities (up to 97% ee) in the Michael addition reactions.
Recommanded Product: 90-44-8. About Anthrone, If you have any questions, you can contact Kumpuga, BT; Itsuno, S or concate me.
