摘要:

AbstractDeprotonation of ethyl (E)‐2‐alkenoates1,3and4yields after protonation the double bond migrated (3Z)‐isomers5,7and9as major products. In contrast, deprotonation and reprotonation of ethyl (Z)‐2‐pentenoate (2) gives the (3E)‐isomer6exclusively. These findings are explained by reaction paths starting from different ester co
