We have developed an electrophilicaddition of allyliccarbocations to 2‐cyclopropylidene‐2‐arylethanols constructing carbon‐carbon bonds with excellent regio‐ and stereoselectivities. The reaction affords 3‐oxabicyclo[3.2.0]heptanes in moderate to good yields via the electrophilicaddition/ring‐opening/vinyl group shift/intramolecular cyclization sequence.
