An Efficient Synthesis of Acetylenic γ- and δ-Hydroxy Ketones, γ- and δ-Keto Acids, and γ-Diketones via Addition of 1-Alkinyllithium Compounds to γ- and δ-Lactones

2-Hydroxy-6-alkyn-5-ones 3, 1-hydroxy-5-alkyn-4-ones 4, and 1-hydroxy-6-alkyn-5-ones 5 are conveniently obtained in exellent yields through a highly selective monoaddition of an 1-alkynyllithium compound 2 to γ-valerolactone (1a), γ-butyrolactone (1b) or

Ring-opening of lactones with alkynyltrifluoroborates: A new route to functionalized α-alkynones

Alkynyltrifluoroborate salts, readily generated in situ by the addition of BF3·OEt2 to alkynyllithiums, were shown to mediate the regioselective acyl C-O ring cleavage of 5-, 6-, and 7-membered lactones. This novel, operationally sim
