Rhodium(II)-Catalyzed One-Pot Four-Component Synthesis of Functionalized Polyether Macrocycles at High Concentration,

ANGEWANDTE CHEMIE, Issue 40 2010
Dr. Walid Zeghida
Vollkommen unerwartet wurde die Rhodium(II)-katalysierte templatfreie Makrocyclisierung von vier Einzelkomponenten in einem Reaktionsgefäß effizienter, wenn die Konzentration erhöht wurde. Daher kondensierten ,-Diazo-,-ketoester mit 1,4-Dioxan, THF oder Tetrahydropyran als Lösungsmittel zu 16- bis 18-gliedrigen Polyethermakrocyclen in bis zu 75,% Ausbeute (siehe Schema; R=Me, Et, PhCH2CH2, Allyl, PhCHCH2).

Four-Component Synthesis of Fully Substituted 1,2,4-Triazoles,

ANGEWANDTE CHEMIE, Issue 2 2010
Steven
Vielfalt en gros: Durch palladiumkatalysierte Carbonylierung wird eine hoch regioselektive Triazolsynthese gestartet. Die drei weiteren Partner, Arylhalogenid, Amidin und Hydrazin, lassen sich einfach variieren, was vollständig substituierte 1,2,4-Triazole in modularer Form zugänglich macht. Das Verfahren wurde zur Synthese wirkstoffartiger und/oder pharmazeutisch wichtiger Moleküle wie Deferasirox genutzt. [source]
