Synthesis of 3-Alkoxycarbonyl-1β-methylcarbapenem by Using the Palladium-Catalyzed C−N Bond-Forming Reaction between Vinyl Halide and β-Lactam Nitrogen
摘要:
3-Alkoxycarbonyl-1beta-methylcarbapenem could be synthesized by using a palladium-catalyzed C-N bond-forming reaction between vinyl halide and beta-lactam nitrogen. In this reaction, the use of Pd(OAc)(2) and DPEphos gave a good result, and the generation of Pd(0) from Pd(OAc)(2) in the absence of a base is necessary to increase the yield.
