The all-syn arylated bicyclo[3.2.0]heptane lactones and non-arylated ones were accessed through palladium-catalyzed C–H activation and C–C cleavage processes, employing MPAA and pyridone-amine ligands, respectively.
Sulfonyl radical-triggered two/three-component tandem bicyclization of CN-containing 1,6-enynes.
This review is planned to provide a comprehensive overview of the progress made in the design and development of chiral ligands for asymmetric gold catalysis.
Efficient synthesis of cyclopropane ring derivatives through the copper-catalyzed cascade reaction of 1,6-enynes using TBHP as both the oxidant and oxygen source.
The development of transition metal-catalyzed [(2+2)+1] and [(2+2)+2] carbocyclization reactions of 1,6-enynes bearing 1,1-disubstituted olefins is discussed, highlighting both the challenges and opportunities for expanding this powerful transformation.
