A flexible approach to γ-alkyl β-htdroxy γ-lactone is described. Tow of the lactones were converted into blastmycinone and trans-whisky lactone respectively. The method features a NaBH4 mediated reductive ring-opening of N,O-acetals, which is obtained via a regioselective Grignard reagent addition with (S)-N,O-dibenzylmalimide followed by lactoneization. The flexibility of the method allows the introduction of various γ-alkyl side chains by Grignard reagents addition.

Key words: (S)-malic acid, blastmycinone, trans-whisky lactone, reduction, Grignard reagent, N,O-acetal
