| Abstract: | An ideal 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 bicyclo3.3.0]octanes in good yields and with excellent selectivities by using simple substrates and conditions. |
