被撤回的出版物: Enantioselective Organocatalytic Hantzsch Synthesis of Polyhydroquinolines (Retracted article. See vol. 23, pg. 3802, 2021)

The four-component Hantzsch reaction provides access to pharmaceutically important dihydropyridines. To expand the utility of this method, we have developed a route under organocatalytic conditions with good yields and excellent ee's. Through catalyst screening, we found that a BINOL-phosphoric acid allowed enantioselective synthesis of six-membered heterocycles with a variety of substitution patterns.
