Participants

Reaction Steps

Into a mixture of 7 g of 2-(6'-carbomethoxyhexyl)-3-cyano-4-hydroxy-2-cyclopenten-1-one, 52.5 ml of acetic acid and 55 ml of 0.5 N hydrochloric acid was added 15 g of zinc powder. After the addition the reaction mixture was stirred for 3 hours under cooling. Thereafter, the zinc powder was removed by filtration, and the filtrate was diluted with water and extracted with ether. The ether extract was washed with a diluted aqueous sodium bicarbonate solution and with water and then dried. The solvent was distilled off to afford 4.5 g of 2-(6'-carbomethoxyhexyl)-3-cyano-4-hydroxy-cyclopentanone.
