Iron-Catalyzed Synthesis of α-Dienyl Five- and Six-Membered N-Heterocycles
摘要:
The iron‐catalyzed synthesis of α‐dienyl N‐heterocycles is reported. The method is cost‐effective, atom‐economic, and led to a range of substituted α‐dienyl heterocycles in moderate to good yields and diastereoselectivities. The α‐dienyl piperidines are key synthetic intermediates as demonstrated by the preparation of a panel of α‐polyenyl N‐heterocycles.
