Funktionalisierung von C‐H‐Bindungen: neue Synthesemethoden für Naturstoffe und Pharmazeutika
TLDR
In this paper, aufsatz gibt einen Uberblick uber die Strategien, die durch Funktionalisierung von C-H-Bindungen eine rasche Synthese von biologisch aktiven Verbindungen wie Naturstoffen und pharmazeutischen Zielsubstanzen ermoglichen.Abstract:
Die direkte Funktionalisierung von C-H-Bindungen in organischen Molekulen hat sich in jungster Zeit zu einer wirksamen und idealen Methode entwickelt, mit der Kohlenstoff-Kohlenstoff- und Kohlenstoff-Heteroatom-Bindungen geknupft werden konnen. Der Aufsatz gibt einen Uberblick uber die Strategien, die durch Funktionalisierung von C-H-Bindungen eine rasche Synthese von biologisch aktiven Verbindungen wie Naturstoffen und pharmazeutischen Zielsubstanzen ermoglichen.read more
