Enantiopure (-)-5-oxoborneol was obtained in 35% overall yield in two steps, starting from readily available (-)-bornyl acetate and using oxone (R) as a safe and inexpensive oxidant. The reported procedure avoids the use of large excess of noxious chromium(VI), which was required by the so far reported syntheses. (C) 2011 Elsevier Ltd. All rights reserved.
