实验步骤: The 3-hydroxy-3-alkylated acetylenic compounds of this invention are prepared by employing the appropriately alkylated alkynyl boron, alkynyl gallium or alkynyl aluminum reactant. For example, treatment of methyl 3-hydroxy-5-oxocyclopent-1-eneheptanoate with tri(3methyl-3-[tetrahydropyran-2-yl]oxy-1-octynyl) aluminum, gallium or boron affords the epimeric methyl 3-hydroxy-2-(3-methyl-3-[tetrahydropyran-2-yl]oxy-1-octynyl)-5-oxocyclopentaneheptanoate. Typically, that compound may be hydrolyzed with a hydrolyzing agent such as hydrolytic acid, e.g. aqueous acetic acid, to yield the instant methyl 3-hydroxy-2-(3-hydroxy-3-methyl-1-octynyl)-5-oxocyclopentaneheptanoate.

实验步骤: To gallium ethoxide (1.06 gram, 0.00517 mol, AlfaAesar 41907) was added methoxyethoxyacetic anhydride (4.16 gram, 0.0167 mol, made by the reaction of methoxyethoxyacetic acid and acetic anhydride). The contents of the reaction mixture were heated to 60° C. for 18 hours to give a viscous liquid mixture of the product and the by-product the ethylester of methoxyethoxyacetic acid. The mixture was soluble and stable in water and in dilute aqueous hydrochloric acid.

实验步骤: 4.1 g of gallium sulphate hydrate (the H2O/Ga2 (SO4)3 molar ratio is close to 25) are dissolved in 3.7 g of distilled water. The sulphate is obtained by dissolving gallium (Grade 1 from Johnson Matthey) in hot concentrated H2SO4, in excess, taking up the suspension obtained in ethanol at a concentration of 60% in water at normal temperature, reprecipitation, in this cooled solution, of gallium sulphate hydrate by adding ether followed by filtration and controlled drying. 1.15 g of 85% phosphoric acid (Prolabo) are added with stirring followed by 0.25 g of 40% hydrofluoric acid (Fluka) and, lastly, 4.55 g of di-n-propylamine (Fluka), abbreviated to DPA in what follows. Stirring is continued for approximately 15 minutes. The pH is then 6.
