9-Ethylenedioxy-15-keto-19-methyl-prost-13,18-dienoic acid, methyl ester → 9-Ethylenedioxy-15-keto-19-methyl-prost-18-enoic acid, methyl ester

Participants

Reaction Steps

To the solution of 3.6 g of 9-ethylenedioxy-15-keto-19-methyl-prost-13,18-dienoic acid, methyl ester, in ethyl acetate (100 ml.) 0.18 g of Pd/C (5%) are added and the mixture is hydrogenated at room temperature under pressure. After absorption of the theoretical quantity of hydrogen the catalyzer is separated by filtration and the solvent evaporated in vacuo to yield 3.4 g of 9-ethylenedioxy-15-keto-19-methyl-prost-18-enoic acid, methyl ester.
