Palladium-Catalyzed One-Pot Synthesis of 2-Alkyl-2-arylcyanoacetates
摘要:
[GRAPHICS]A one-pot procedure for the synthesis of 2-alkyl-2-arylcyanoacetates based on a Pd(OAc)(2)/DPPF (DPPF = 1,1'-diphenylphosphino ferreocene)-catalyzed enolate arylation followed by in situ alkylation has been developed. This procedure tolerates a diverse range of aryl and heteroaryl bromides, and provides a rapid entry to a variety of 2-alkyl-2-arylcyanoacetates in good to excellent yield.
