A simple and efficient copper-catalyzed method for synthesis of naphthols containing multifunctional groups has been developed under mild conditions (room temperature to 60 °C), and it can tolerate various functional groups.
Fluspidine is a high affinity ligand of the σ1 receptor. To further improve the ligand affinity, fluspidine analogs were systematically synthesized and screened herein. To design the modified ligand analogs, a docking simulation of the protein–ligand complex structure was examined. By using the developed synthetic strategy involving asymmetric catalytic 1,4-reduction of α,β -unsaturated carboxylic
