We describe the first metal-free and organocatalytic strategy to access highly functionalised dibenzocycloheptanesviaa phosphine-promoted annulative Morita-Baylis-Hillman (MBH) reaction. The method is manipulated to access to chiral dibenzocycloheptanes as well. This work represents a rare entry for the construction of seven-membered carbocyclesviathe MBH route. The realisation of several bioactive molecules possessing the dibenzocycloheptane core makes this an attractive strategy.

An efficient protocol for the straightforward, single-step synthesis of 3-aryl-1-indanones from 2′-iodochalcone via reductive Heck reaction using phosphine free, stable and reusable binaphthyl stabilized palladium nanoparticle (Pd-BNP) as a catalyst has been described. An immense array of substrate scope with electron-rich and deficient 2′-iodochalcones have been synthesized. Further derivatization of product indanones have been achieved successfully. The heterogeneous nature of the Pd-BNP has been validated by centrifugation test and mercury poisoning experiment. Pd-BNP has been successfully recycled up to 5 cycles without any significant loss in reaction yield and particle size of nanoparticles, confirmed by TEM analysis. (Figure presented.).

The Buchwald-Hartwig coupling/Michael addition sequence has been successfully applied to the synthesis of functionalized 1,2-disubstituted 4-quinolones using Pd(OAc)2 as a catalyst and PPh3 as a ligand. Under these conditions, the intermediate products first formed from chalcones and primary amines underwent catalytic dehydrogenation to yield the 1,2-disubstituted 4-quinolones. Copyright
