WebJun 21, 2002 · After the transfer of the chromyl acetate solution was complete, some residual chromium trioxide remained. The residual material was dissolved, while cooling, in additional acetic acid/acetic anhydride solution (20–30 mL) and then transferred via canula to the 1,8-cineole solution. Weboxidation with chromyl acetate [5,6] which affords racemic 3-oxocineole 2 owing to the symmetry of 1. In contrast, naturally occurring oxygenated derivatives have been reported sporadically, mainly as metabolites from living organisms fed on cineole containing food [8-11] such as in the urine of some
