    • Only slight decomposition was observed when compound 3 was stored at -18°C for 10 months, while storing at 0°C led to complete decomposition in less than 3 months.

    • note
    • The best yields achieved in the deprotection step were around 70%, confirming an obvious assumption that γ-alkylidene butenolides are also acid sensitive.
