    • note
    • In order to transform the organomercurial compound 2a into the corresponding structurally rigid lactone, hydrolyses of the ketal were made with 5% HCl solution in THF and with AcOH in THF producing the starting α,β-unsaturated ester 5a. However, the acid condition led to product 5a during the purification by column chromatography on silica gel of 2a.
