    Gold-Catalyzed Formation of Pyrrolo- and Indolo-Oxazin Derivatives: the Key Structure of Some Marine Natural Products
    (Beilstein-institut, 2015) Taskaya, Sultan; Menges, Nurettin; Balci, Metin
    Various N-propargylpyrrole and indolecarboxylic acids were efficiently converted into 3,4-dihydropyrrolo- and indolo-oxazin-1-one derivatives by a gold(III)-catalyzed cyclization reaction. Some of the products underwent TFA-catalyzed double bond isomerization and some did not. Cyclization reactions in the presence of alcohol catalyzed by Au(I) resulted in the formation of hemiacetals after cascade reactions.
