Hydroxy ketones

In organic chemistry a hydroxy ketone (often referred to simply as a ketol) is a functional group consisting of a ketone flanked by a hydroxyl group. In the two main classes, the hydroxyl group can be placed in the alpha position (an alpha-hydroxy ketone RCR′(OH)(CO)R) or in the beta position (a beta-hydroxy ketone, RCR′(OH)CR2(CO)R).
