Efficient Synthesis of Cyclopropane‐Fused Heterocycles with Bromoethylsulfonium Salt. Issue 33 (10th July 2013) - Fritz, Sven P.
Abstract Lord of the rings! [3.1.0] bicyclic ring systems were synthesized using bromoethylsulfonium triflate and easily available amino acid/aza‐Morita–Baylis–Hillman‐derived allylic amines. The simple transformation displays a very high degree of diastereoselectivity and enables access to a diverse range of densely substituted pyrrolidine‐based bicycles.
