An unconventional, highly stereoselective, and regioselective intramolecular oxypalladation/acyloxylation cascade of alkyne-tethered cyclic 1,3-diones has been developed. This atom-economic Pd(II)-catalyzed annulation reaction is initiated by the oxypalladation alkyne with an internal carbonyl group via 5-exo-dig cyclization instead conventional acetoxypalladation pathway. In this process, carboxylic acid plays a pivotal role in generation active cationic Pd-complex subsequent acyloxylation proto-demetalation steps. Additionally, method enables asymmetric using chiral bidentate BOX ligand, achieving enantiomeric ratios ≤93:7.

Larock isoquinoline synthesis is one of the most efficient and straightforward approaches to construction 3,4-disubstituted isoquinolines. However, there have been no asymmetric versions for axially chiral isoquinolines since their initial report in 2001. Herein, we documented first example an by employing Pd(OAc)

Abstract A class of novel chiral‐bridged biphenyl monophosphine ligands with a benzofuran moiety ( He‐phos ) has been successfully synthesized and reported. These exhibited good performance in the gold‐catalyzed enantioselective cycloaddition reaction 2‐(1‐alkynyl)‐2‐en‐1‐ones nitrones, resulting successful preparation series polyaryl‐substituted heterocyclic compounds high enantioselectivities (up to 99% yield, 98% ee). The wide substrate adaptability (53 examples) mild conditions demonstrate practicability this reaction.
