Stereoselective Synthesis of 3-Alkylcinnamonitriles
摘要:
Stereoselective synthesis of (2Z)-3-arylselenocinnamonitriles and coupling them with Grignard reagents catalysized by CuI, giving the trisubstituted alkenes with main retention products.
Using the palladium/2-(dicyclohexylphosphino)-2′,6′-di(isopropoxy)biphenyl (RuPhos) catalyst, aryl halides and tricyclohexylsilyl selenol can be efficiently coupled to the respective aryl tricyclohexylsilyl selenides. These can be transformed in the same reaction vessel to the corresponding selenoacetates, permitting a straightforward access to a range of molecules potentially useful for materials

rhodium-catalyzed reaction of triazoles with acyl selenides. Under thermal reaction conditions and in the presence of a rhodium catalyst, a rapid 1,3-difunctionalization reaction occurs to provide valuable α-seleno enamides with high stereoselectivity and broad functional group tolerance, which was demonstrated in 35 examples with up to 95% yield. Computational calculations suggest a reaction pathway that
