摘要:A Two-Step Protocol Has Been Developed For The Introduction Of Cyanomethylene Groups To Metalated Aromatics Through The Intermediacy Of Substituted Isoxazoles. A Palladium-Mediated Cross-Coupling Reaction Was Used To Introduce The Isoxazole Unit,Followed By Release Of The Cyanomethylene Function Under Thermal Or Microwave-Assisted Conditions. The Intermediate Isoxazoles Were Shown To Be Amenable To Further Functionalization Prior To Deprotection Of The Sensitive Cyanomethylene Motif,Allowing Access To A Wide Range Of Aryl-And Heteroaryl-Substituted Acetonitrile Building Blocks.
