REACTION OF 2,2-DISUBSTITUTED CYCLOPENTANONES WITH BROMINE AND ALKALI : FACILE PREPARATION OF 5,5-DISUBSTITUTED 2-HYDROXYCYCLOPENTANONES AND TRANSFORMATION TO THE 3,3-DISUBSTITUTED CYCLOPENTANONES
Reaction of 2,2-disubstituted cyclopentanones (1a-1d) with bromine followed by aqueous alkali furnishes the 5,5-disubstituted 2-hydroxycyclopent-2-en-1-ones which were transformed to the 3,3-disubstituted cyclopentanones by reduction with hydriodic and acetic acids.
