The syntheses of a number of C ‐aryl‐ N ‐3‐butenyl nitrones [aryl ring=4‐CH 3 O‐phenyl ( 1a ), phenyl ( 1b ), 4‐Cl‐phenyl ( 1c ), 4‐Br‐phenyl ( 1d ), 4‐NO 2 ‐phenyl ( 1e ), 2‐furyl (1f), 2‐thienyl ( 1g ), 2‐pyrryl ( 1h )] and their thermochemical reactions have been investigated. The thermocycloadditions of 1a–1h are regiospecific in forming a novel heterobicyclic ring system, exo ‐aryl‐1‐aza‐7‐oxabicyclo‐[2.2.1]heptane.
