The synthesis of polyfunctionalized fused aromatic carbo- and heterocycles from aryl iodides and bromoenoates via a tandem palladium-catalyzed aromatic substitution intramolecularHeck sequence is reported. Using Pd(OAc)2 and tri-2-furylphosphine (TFP) in the presence of norbornene and Cs2CO3 in CH3CN at 85 °C gave a variety of functionalized bi- and tricyclic fused aromatic rings in good yield.
报道了通过串联钯催化的芳族取代分子内Heck序列由芳基碘化物和溴烯酸酯合成多官能化稠合的芳族碳和杂环。在85°C的CH 3 CN中,在降冰片烯和Cs 2 CO 3存在下,使用Pd(OAc)2和三-2-呋喃基膦(TFP),可以得到多种官能化的双环和三环稠合芳环。
