Abstract
A process for the preparation of R.alpha.-cyclopentenoids and then R.alpha., R.omega.-cyclopentanoids is described. The process involves the reaction of a compound of the formula ##STR1## where X is halo, particularly Br or I and P is a protecting group with an alkylborane to produce the R.alpha.-cyclopentenone. The R.alpha.-cyclopentenone is reacted with a R.omega. cuprate to produce the R.alpha., R.omega.-cyclopentenoid. The process is used for the preparation of prostaglandins which are known pharmaceutically active compounds.
