A series of PdII-quincorine and -quincoridine complexes in which the ligands are coordinated through N,O-donor atoms have been synthesised, and their structural features determined by X-ray crystallography. Additionally, new chiral tetradentate N,P-ligands containing two quinuclidine cores bridged through a cis-enediyne fragment have been obtained. The different coordinating properties of the new ligands

coupling by MacMillan. Inspired by this method, we report herein its first utilization in natural product total synthesis through realizing the coupling of 4-bromo-quinoline or 4-bromo-6-methoxyquinoline with quincorine or quincoridine, respectively. The alcohols were denovo synthesized in racemic form by a key step of the intramolecular Diels–Alder reaction or in an enantioselective manner by Ir/amine
