Neue Entwicklungen auf dem Gebiet der Minisci‐Reaktion

Abstract: Reaktionen, die über die Addition von kohlenstoffzentrierten Radikalen an basische Heteroarene gefolgt von der formalen Abspaltung eines Wasserstoffatoms verlaufen, sind heute allgemein als Minisci‐Reaktionen bekannt. Als synthetisches Werkzeug erstmals in den 1960er Jahren von Minisci entwickelt, wurde diese Reaktion in den letzten fünfzig Jahren kontinuierlich genutzt, um Heterozyklen schnell und direkt zu funktionalisieren, ohne dass eine De‐novo‐Synthese von Heterozyklen nötig ist. Während die meisten der … Show more

“…C-H alkylation of heteroarenes, known as Minisci reaction, is a well-established synthetic tool for C(sp 2 )-C(sp 3 ) bond formation. 1 It enables direct, late-stage modification of aromatic heterocycles, which are omnipresent structural motifs in various natural products, pharmaceuticals and agrochemicals. 2 The Minisci reaction involves generation of carbon-centered alkyl radicals and their addition to an electron-deficient heteroaromatic ring, which is accompanied by a formal loss of the hydrogen atom.…”

“…In recent years, there have been numerous reports of radical/homolytic functionalization of pyrimidines as a mild and functional group tolerant alternative to deprotonative metalation. [7] Several notable examples of this strategy have allowed the predictable, selective and mild functionalization of pyrimidines under photoredox catalysis and Minisci conditions. [8] While this approach is powerful for pyrimidine alkylation and (electron-rich) arylation at C4 due to the innate electrophilicity of this ring position, metalation would prove complementary to this strategy and so more robust C4 metalated pyrimidine derivatives would make a welcome addition to the arsenal of methods available for pyrimidine functionalization.…”
