Abstract
A process for forming 4-ketocyclopentene and substituted 4-ketocyclopentene compounds starting from the corresponding 1-carbohydrocarbyloxy-2-keto-4-hydroxy-5-cyclopentene by reduction followed by decarboxylation.
Claims3
A process for forming a 4-ketocyclopentene compound comprising reducing a 1-carbohydrocarbyloxy-2-keto-4-hydroxy-5-cyclopentene compound by contacting with zinc and decarboxylating the resulting reaction product by contacting the reaction mixture with a mixture of an organic acid and an inorganic halide.
