    • note
    • 9 By using NaH in THF in the absence of a proton source, the conjugate addition leads to an equilibrium mixture and product 3, more stable, is mainly formed under thermodynamic control. On the contrary, when sodium ethoxide in ethanol is employed, the anion arising from conjugate addition immediately undergoes protonation by the solvent, so that product 4 is mainly formed under kinetic control. Studies are in progress in order to attain a deeper insight about this behaviour and for possible extension of the method to the synthesis of bioactive compounds, and will be reported in due course.

    • The cyclisation was also performed starting from mesylate 8, but in this case bicyclic compound 9 was isolated in only 53% yield.
