Palladium(0)-Catalyzed Cross-Benzannulation between Conjugated Enynes. Reactivity-Controlled Synthesis of Multifunctionalized Benzenes
摘要:
[GRAPHICS]The synthesis of multifunctionalizbenzenes such as polysubstituted alkoxycarbonyl- or cyanostyrenes was carried out by the regioselective cross-benzannulation between conjugated enynes in the presence of Pd(PPh3)(4).
