Using catalytic Bi(OTf)3, isatogens react efficiently with styrenes, releasing CO in a unique reaction cascade that leads to a novel synthesis of 2,4-diarylquinolines—a breakthrough in isatogen chemistry!

Bi(OTf)3-Catalyzed Cascade Cycloaddition–Decarbonylation–N-Deoxygenative Aromatization between 2-Arylisatogens and Styrenes: Unveiling a Synthesis of 2,4-Diarylquinolines
An unprecedented Bi(OTf)3-catalyzed reaction between 2-arylisatogens and vinylarenes to yield 2,4-diarylquinolines is reported. The transformation occurred via a BiIII-coordination to the embedded anionic nitrone oxygen, which induced a regiospecific stepwise formal [4 + 2]-cycloaddition with vinylarenes to yield a strained tricyclic intermediate, which subsequently extruded gaseous carbon monoxide. N-Deoxygenative aromatization ensued to produce 2,4-diarylquinolines. The protocol was applicable to a variety of substrates to produce the quinolines in up to an 89% yield.

This #ChemEd #Chemistry #ChemSky summary introduces 1,3-dipolar cycloadditions. It builds on the Diels-Alder 1 pagers & is another [4+2] cycloaddition but gives 5-membered rings. It is only an intro. More details will be on makingmolecules.com as soon as I've typed up my notes. Enjoy!
A one page summary of 1,3-dipolar cycloadditions. It starts with an introduction covering the general reaction and classifying 1,3-dipoles as either linear or bent. There are then four examples; nitrile oxide-alkene cycloadditions, nitrone-alkene cycloadditions, azide-alkyne cycloadditions and azomethine ylide cycloadditions (my favourite). The discussion of the azide reaction mentions the original pericyclic reaction and the catalysed variant that won the Nobel Prize.

Marano, fugge all’alt dei militari: 22enne preso con pistola e coltelli
Marano di Napoli – Era pronto per un raid armato il giovane 22enne bloccato dopo un inseguimento dei carabinieri e trovato in possesso di una pistola, due coltelli e guanti neri. Raffaele Nitrone, già noto alle forze dell’ordine, è stato arrestato dai Carabinieri della Compagnia di Marano di Napoli insieme...

9. Det finnes de som mener at heterodoks økonomi på en eller annen måte er omstridt eller "utenfor" faget på en måte. Det er ikke riktig, men det er en annen måte å se på faget enn nyklassisk. Og det er jo fint.

Jeg har diskutert med noen som mente at det heterodokse var utenfor faget før:
