Design and Synthesis of 5''-Iodoneplanocin A and Its Analogues as Potential S-Adenosylhomocysteine Hydrolase Inhibitor
5"-Iodoneplanocin A (1) and its analogues 2 and 3 were designed and synthesized as potential SAHH inhibitor via iodocyclopentenol 6, which was prepared using a Michael addition-iodination-elimination…
Consecutive condensation, C-N and N-N bond formations: a copper- catalyzed one-pot three-component synthesis of 2H-indazole.
2H-Indazoles are synthesized using copper-catalyzed, one-pot, three-component reactions of 2-bromobenzaldehydes, primary amines, and sodium azide, which has a broad substrate scope with a high tolerance for a variety of functional groups.
Pd-catalyzed carbonylative reactions of aryl iodides and alkynyl carboxylic acids via decarboxylative couplings.
The desired carbonylative coupling was formed from phenyl propiolic acid without any formation of a noncarbonyLative coupling product in the absence of CuI, but the reaction with alkyl-substituted alkynyl carboxylic acids required CuI as a cocatalyst for high yield.

Diarylalkynones were synthesized from one-pot Pd-catalyzed carbonylative and noncarbonylatives coupling reactions of propiolic acid with aryl iodides under a carbon monoxide atmosphere, which afforded good yields and functional group tolerance.
Synthesis of benzoylacetonitriles from Pd-catalyzed carbonylation of aryl iodides and trimethylsilylacetonitrile.
This preparation method provides good yields of the carbonylated products without any additional ligands and has a broad substrate scope with a high tolerance for a variety of functional groups.
Palladium-Catalyzed Carbonylation with Mo(CO)6 for the Synthesis of Benzoylacetonitriles
Benzoylacetonitriles were synthesized by the palladium-catalyzed carbonylation of aryl iodides and trimethylsilylacetonitrile using Mo(CO)6 as a carbon monoxide source. Pd(PPh3)Cl2 and CuF2 were…
