Use of the Stille Coupling Reaction on Heteroaromatic Cations: Synthesis of Substituted Quinolizinium Salts
摘要:
[GRAPHICS]We describe the first efficient application of the Stills coupling reaction on heteroaromatic cations. In the presence of Pd(0)/Cul, the reaction of bromoquinolizinium salts and Various tributylstannyl compounds proceeds in satisfactory yield under mild reaction conditions, affording different substituted quinolizinium salts.
