متن کاملAminoketone Rearrangements . 11 . The Rearrangement of Phenyl a - Aminoketonesl
Phenyl a-aminoketones have been shown to undergo carbon skeleton rearrangement to unconjugated aminoketones when heated a t 200-240". The probable intermediate is an unconjugated hydroxyimine formed by base removal of an amine hydrogen and migration of an alkyl group. The hydroxyimine can subsequently rearrange by base removal of a hydroxyl proton and migration of the phenyl grouping. An amine ...
متن کاملPhoto-Fries rearrangement of aryl acetamides: regioselectivity induced by the aqueous micellar green environment.
Photochemical reactions tend to give more than one photoproduct. However, such a reaction can be a powerful synthetic tool when it is possible to conduct it in regioselective conditions yielding a single photoproduct. Water-surfactant solutions as reaction media can be considered as an approach in this context because they show products with different features than those from isotropic solution...
متن کاملTotal syntheses of oxygenated brazanquinones via regioselective homologous anionic Fries rearrangement of benzylic O-carbamates
Using new variations of anionic aromatic chemistry, the total synthesis of oxygenated brazanquinones (1a-1c), derived from beta-brasan, a natural product isolated from Caesalpina echinata, via carbamates 2a-2c is described.
متن کاملThe mycological legacy of Elias Magnus Fries
The taxonomic concepts which originated with or were accepted by Elias Magnus Fries were presented during his lifetime in the printed word, illustrative depiction, and in collections of dried specimens. This body of work was welcomed by the mycological and botanical communities of his time: students and associates aided Fries and after his passing carried forward his taxonomic ideas. His legacy...
