Palladium‐Catalysed Cross‐Coupling Reactions for the Synthesis of Chalcones

“…Propargyl alcohol derivatives have also been used as precursors for isomerization reaction or through the Meyer‐Schuster rearrangement to produce the corresponding enones. On the other hand, a particular propargyl amine derivatives could also be transformed to chalcones when irradiated under microwaves in the presence of montmorillonite doped with copper (I) chloride and water . Recently, there is a large in‐flux of data available regarding the use of cross‐coupling palladium‐mediated, e. g. Heck‐Mizoroki coupling, Suzuki‐Miyaura coupling, Stille coupling, Hiyama coupling, Sonogashira coupling and Tsuji‐Trost coupling reactions in the synthesis of chalcones.…”

Microwave-assisted expeditious and efficient synthesis of novel quinolin-4-ylmethoxychromen-2- and -4-ones catalyzed by YbCl3under a solvent free one-pot three component domino reaction and their antimicrobial activity

“…Therefore, various methods have been reported over the past 130 years for their synthesis that includes Skraup, 8 Doebnervon Miller, 9 Ptzinger, 10 Conrad-Limpach, 11 Combes 12 and Friedländer syntheses. 13 Recently, different catalysts such as CuCl, 14 CuBr, 15 Cu(OTf) 2 , 16 InCl 3 , 17 FeCl 3 , 18 Fe(OTf) 3 , 19 AgOTf, 20 AuCl 3 /CuBr, 21 NbCl 5 , 22 Yb(p) 3 , 23 CuI/La(OTf) 3 , 24 montmorillonite K-10 (ref. 25) for the A 3 -coupling reaction of alkyne, aldehyde and amine have been explored.…”
