Stereochemistry of the Reactions of CuI Catalyzed Grignard Reagents with Ethyl (E)- and (Z)-β-Chlorocinnamates

Jalander, Lars,Broms, Merete

, p. 173 - 178 (2007/10/02)

Ethyl (E)- and (Z)-3-chloro-3-phenyl-2-propenoate were prepared and separated.The (Z)-isomer gave β-alkylated ethyl cinnamates in good yield when reacted with alkyl Grignard reagents in the presence of 10percent CuI.The (Z)-isomer reacted with retention o
