Over the course of our survey, certain substrates behaved a bit differently than expected (Scheme 5A). With sulfamate epoxide 36, seven-membered ring 37 was the major product, forming in a 70% isolated yield. Here, the epoxide carbon attached to the aryl ring is highly activated for SN2 attack, and this likely underlies formation of an unusual sevenmembered ring in good yield. With tosylate substrate 39, tandem nucleophilic attacks took place to form pyrrolidine 40 in a single transformation.
