Cyclisations de Vilsmeier-Haack et de Mannich en cascade sur un amide chimiosélectivement activé application à la synthèse totale du («)-sécurinol B

Larouche-Gauthier, Robin (Université de Sherbrooke, 2009)

Les travaux de recherches présentés dans cette thèse ont pour but le développement d'une nouvelle stratégie générale de synthèse d'alcaloïdes polycycliques via une cascade de cyclisations de Vilsmeier-Haack et de Mannich ...

Asymmetric total synthesis of (+)-virosine a via sequential nucleophilic cyclizations onto an activated formamide

Bélanger, Guillaume; Dupuis, Marianne; Larouche-Gauthier, Robin (2012)

Abstract: The first synthesis of tetracyclic alkaloid virosine A is reported. The natural alkaloid was prepared in only 13 steps, in an enantioenriched form. The azabicyclo[2.2.2]octane core was efficiently assembled using ...

Intramolecular additions of various π-nucleophiles to chemoselectively activated amides and application to the synthesis of (±)-tashiromine

Bélanger, Guillaume; Larouche-Gauthier, Robin; Ménard, Frédéric; Nantel, Miguel; Barabé, Francis (2006)

Abstract: Vilsmeier-Haack type cyclizations proved to be particularly efficient for generating parts of the polycyclic cores of many alkaloids, although only monocyclizations have so far been reported. With the goal ...
