Abstract: Abstract 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… read more here.
