Cinchona officinalis (Rubiaceae) is an endemic species of the Loja Valley in southern Ecuador with medicinal uses. Because of over-exploitation in the nine- teenth century and more recent disturbances to its ecosyst...
The cinchona alkaloids catalyzed the direct asymmetric Mannich reactions of 1, 3-dicarbonyl compounds with acyl imines to produce novel β-amino ester derivatives containing a quinazoline moiety. The adducts were isol...
The self-assembly of the precatalyst modules, which are amino acids and cinchona alkaloid derivatives, leads to the direct formation of the desired organocatalysts without any synthesis. These modularly designed organ...
Asymmetric hydrogenation of (6-methoxyl-2-naphthyl)-2-acrylic acid catalyzed by cinchona modified Pd(0)-a-FeOOH was reported and ee抯 of (S)-(+)-2-(6′-methoxyl-2-naphthyl) propionic acid ((S)-(+)-naproxen) up to 98% ...
