Title: Palladium-catalyzed cyclization of bromoenynamides to tricyclic azacycles: synthesis of trikentrin-like frameworks. Author: Campbell CD, Greenaway RL, Holton OT, Chapman HA, Anderson EA. Journal: Chem Commun (Camb); 2014 May 25; 50(40):5187-9. PubMed ID: 23969613. Abstract: Palladium-catalyzed cascade cyclization of bromoenynamides equipped with an additional alkyne or ynamide substituent affords azatricyclic products. Using 5- to 7-membered ring tethers, this chemistry offers a regiospecific route to highly-functionalized azacycles. Elaboration to the trikentrin B skeleton is achieved from the arylsilane cyclization products.[Abstract] [Full Text] [Related] [New Search]
