Participants

Reaction Steps

5-Acetoxy-2-(3-acetoxyoctyl)cyclopent-2-enone (15.5 g.) [prepared as described in (h) above], acetone cyanohydrin (6.0 g.), aqueous sodium carbonate solution (10.0% w/v; 5 ml.) and methanol (75 ml.) were stirred together and heated at reflux for 4 hours. Methanol was removed in vacuo, water (50 ml.) was added and the mixture extracted with diethyl ether. The ethereal extract was washed with water, dried with magnesium sulphate and evaporated in vacuo to give 2-(3-acetoxyoctyl)-3-cyano-5-hydroxycyclopentanone (14.3 g.) which was used as starting material in the following preparation (k) of 3,4-dihydroxy-2-(3-hydroxyoctyl)cyclopentane carbonitrile without further purification.
