Procedure: Octene-1 in an amount of 2.24 g. and 11.65 g. of manganic acetate, Mn(C2H3O2)3. 2H2O, (comprising two equivalents of Mn+3 based on titration value), were refluxed under nitrogen in 200 ml. propionic acid containing 20 g. potassium propionate. In less than an hour a good yield of alphamethyl-gamma-n-hexyl-butyrolactone was obtained.

Procedure: Styrene in an amount of 2.1 grams and 11.65 grams of manganic acetate, Mn(C2H3O2)3.2H2O, comprising two equivalents of Mn+3 based on titration value, were refluxed under nitrogen in 200 milliliters of propionic acid containing 20 grams of potassium propionate. In less than an hour, a 50% yield of alpha-methyl-gamma-phenyl butyrolactone was obtained. In less than an hour

Procedure: At 135° C., 122 g of 4-hydroxybenzaldehyde, 163 g of propionic anhydride and 112 g of potassium propionate were reacted with stirring for 30 hours, the reaction mixture was dropped into 1.5 l of distilled water, and sodium carbonate was added to form an aqueous alkaline solution. The unreacted 4-hydroxybenzaldehyde was removed and concentrated hydrochloric acid was added to render the solution acidic and precipitate the reaction product. The precipitate was recovered by filtration and washed with water to obtain 85 g of a crude product. The precipitate was dissolved in a solution comprising 150 g of water, 150 g of ethanol and 30 g of sodium hydroxide, and the solution was refluxed for 2 hours and dropped into a liquid comprising concentrated hydrochloric acid and ice to precipitate the reaction product. The precipitate was recovered by filtration, washed repeatedly with distilled water and dried to obtain 61 g of crude 4-hydroxy-α-methylcinnamic acid. A product (refined 4-hydroxy-α-methylcinnamic acid) obtained by recrystallizing this crude 4-hydroxy-αmethylcinnamic acid from hot water was used for the subsequent reaction. was added to form an aqueous alkaline solution The unreacted 4-hydroxybenzaldehyde was removed concentrated hydrochloric acid was added precipitate the reaction product The precipitate was recovered by filtration washed with water to obtain 85 g of a crude product The precipitate was dissolved in a solution the solution was refluxed for 2 hours to precipitate the reaction product The precipitate was recovered by filtration washed repeatedly with distilled water dried

Procedure: In a mixture of 50 ml of acetone and 12 ml of water are dissolved 2.5 g of 16β-ethyl-17β-bromoacetoxy-4-estren-3-one and 0.7 g of potassium propionate. The solution is stirred at room temperature (17°-25° C.) for 3 days and concentrated under reduced pressure. The residue is extracted with 200 ml of ethyl acetate. The organic layer is separated, washed with water and saturated aqueous sodium chloride and dried over anhydrous magnesium sulfate. The solvent is distilled off under reduced pressure and the residue is subjected to column chromatography. Following passage of 1000 ml isopropyl ether-n-hexane (2:3), elution is carried out with 2000 ml of the same solvent system. The eluate is evaporated under reduced pressure to remove the solvent, giving 0.87 g of the above-identified compound as white crystals. concentrated under reduced pressure The residue is extracted with 200 ml of ethyl acetate The organic layer is separated washed with water and saturated aqueous sodium chloride dried over anhydrous magnesium sulfate The solvent is distilled off under reduced pressure passage of 1000 ml isopropyl ether-n-hexane (2:3), elution The eluate is evaporated under reduced pressure to remove the solvent
