stereoselective insertion of in situ generated benzynes into lawsones through domino formal [2+2]‐cycloaddition followed by rearrangement is disclosed. The reaction allowed for the preparation of biologically important benzannulated bicyclo[3.3.0]octanes in good yields and with excellent selectivities by using simple substrates and conditions.
