“…Here, we report the first complete chloroplast (cp) genome of Cinchona officinalis. This cp genome has a 156,984 bp in length with typical quadripartite structure, containing a large single copy (LSC) region (83,929 bp) and an 18,051 bp small single-copy (SSC) region, separated by two inverted repeat (IR) regions (27,502 bp). …”

“…We present molecular insights into a one-pot catalytic Michael reaction cascade between a dicarbonyl compound (7-oxo-7-phenylhept-5-enal) and nitrostyrene, catalyzed by two chiral organocatalysts (proline and cinchona-thiourea), leading to a densely functionalized tetra-substituted cyclohexane product. …”

“…These activated dithioesters have shown excellent reactivity in an aminolysis reaction from simple or more complex primary amines such as cinchona alkaloids. A stoichiometric amount of amine was sufficient to prepare various thioamides, including a 4-styrenylthioamide cinchonidine monomer, under environmentally friendly conditions, at room temperature, and in a very short time.…”
