    • note
    • The alkylation step (cf. 80 → 81) resulted in cyclopropane formation when an expressed ester was present (selective reaction of the ester enolate). Also, an expressed ketone on the spiropyran unit was not tolerated during this reaction, requiring reduction of 78 to 79. Fortunately, no protection of 79 was necessary. Details will be presented in a separate paper.
