A Rare Gamma-Pyranopyrazole Skeleton: Design, One-Pot Synthesis and Computational Study
Özet
Drawing upon a consecutive amide coupling and intramolecular cyclisation pathway, a one-pot, straight-forward synthetic route has been developed for a range of pyrazole fused gamma-pyrone derivatives. The reaction mechanism proposed for the chemoselective formation of gamma-pyranopyrazole is furthermore fully supported by experimental and computational studies.
