Two series of (dfppy)2Ir(LN^O) with different substituents were designed and successfully synthesized and the effect of substitution at the ancillary ligand on the photophysical and electrochemical properties of (dfppy)2Ir
One-Pot Synthesis of Benzo[4,5]imidazo[1,2-a]pyrimidin-2-ones Using a Hybrid Catalyst Supported on Magnetic Nanoparticles in Green Solvents
Moussa, Alkassoume,Rahmati, Abbas
, p. 764 - 774 (2021)
The conversion of soluble polyoxometalate into insoluble polyoxometalate is considered to be one of the major challenges in synthetic organic chemistry. Here, polyoxometalate was bonded to the salt part of an organic branch immobilized on the silica-coate
Base-Catalyzed Tandem Cyclization: Diastereoselective Access to the 3,4-Dihydroisoquinolin-2(1 H)-one Core
Shirsat, Prashishkumar K.,Khomane, Navnath B.,Meshram, Sneha H.,Sridhar, Balasubramanian,Meshram, Harshadas M.,Kumbhare, Ravindra M.

A novel, one-pot reaction for the synthesis of 3,4-dihydroisoquinolin-2(1 H)-one derivatives is developed via a base-mediated three-component reaction of ninhydrin, aniline and acetylenic esters. This diastereoselective reaction takes place in methanol at 70A °C under transition-metal-free conditions, and direct construction of the C-N and C-C bonds is readily achieved via tandem cyclization. These cyclic frameworks are resourceful small molecular keys to many natural products.
Synthesis, crystal structure and dft studies of polyfunctionalized alkenes: A transition metal-free c(sp2)-h sulfenylation of electron deficient alkyne

Salvaggio, Flavia,Hodgkinson, James T.,Carro, Laura,Geddis, Stephen M.,Galloway, Warren R. J. D.,Welch, Martin,Spring, David R.
, p. 434 - 437 (2016)
The synthesis of four quinolone natural products from the actinomycete Pseudonocardia sp. is reported. The key step involved a sp2-sp3 Suzuki-Miyaura reaction between a common boronic ester lateral chain and various functionalised quinolone cores. The quinolones slowed growth of E. coli and S. aureus by inducing extended lag phases. The total synthesis of four quinolone natural products is reported. The quinolones were synthesised in a highly efficient and direct manner from various readily prepared quinolone cores and a common boronic ester lateral chain. The key step involved a challenging sp2-sp3 Suzuki-Miyaura reaction.
Synthesis of Natural and Unnatural Quinolones Inhibiting the Growth and Motility of Bacteria
