A novel, facile, and expeditious two-step synthesis of 3,4-unsubstituted isoquinolin-1(2H)-ones from a Suzuki cross-coupling between 2-halobenzonitriles and commercially available vinyl boronates followed by platinum-catalyzed nitrile hydrolysis and cyclization is described.

Paragraph 0012; 0037-0039; 0061-0063, (2020/02/19)
The invention discloses aromatic compounds and a preparation method and application thereof. The preparation method of the aromatic compounds includes the step of performing a cyclization reaction between an amide compound and a benzoic acid compound in the presence of a rhodium catalyst, a metal oxidant and base, wherein the aromatic compounds are isoquinolinone compounds or isocoumarin derivatives, and the amide compound is N-vinylformamide or N-vinylacetamide. Through the synergistic effect of the rhodium catalyst, the metal oxidant and the base, the isoquinolinone compounds or isocoumarinderivatives are obtained through the one-step reaction between the benzoic acid compound and the amide compound. The reaction has simple operation, the raw materials are cheap and easily available, reaction substrates can be selected flexibly according to the required isoquinolinone compounds and the isocoumarin derivatives, and the synthesized isoquinolinone compounds and the isocoumarin derivatives can be used as a backbone structure in multiple biologically active molecules and natural products, and have high practicality.
Rhodium(III)-catalyzed C-H activation/annulation with vinyl esters as an acetylene equivalent
Webb, Nicola J.,Marsden, Stephen P.,Raw, Steven A.
, p. 4718 - 4721 (2015/04/27)
The behavior of electron-rich alkenes in rhodium-catalyzed C-H activation/annulation reactions is investigated. Vinyl acetate emerges as a convenient acetylene equivalent, facilitating the synthesis of sixteen 3,4-unsubstituted isoquinolones, as well as select heteroaryl-fused pyridones. The complementary regiochemical preferences of enol ethers versus enol esters/enamides is discussed.
