SDS of cas: 34941-92-9. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 4-Chloro-2-fluoropyridine, is researched, Molecular C5H3ClFN, CAS is 34941-92-9, about Total Synthesis of (-)-Maximiscin. Author is McClymont, Kyle S.; Wang, Feng-Yuan; Minakar, Amin; Baran, Phil S..
A short, enantioselective synthesis of (-)-maximiscin (I), a structurally intriguing metabolite of mixed biosynthetic origin, is reported. A retrosynthetic anal. predicated on maximizing ideality and efficiency led to several unusual disconnections and tactics. Formation of the central highly oxidized pyridone ring through a convergent coupling at the end of the synthesis simplified the route considerably. The requisite building blocks could be prepared from feedstock materials (derived from shikimate and mesitylene). Strategies rooted in hidden symmetry recognition, C-H functionalization, and radical retrosynthesis played key roles in developing this concise route.
