✦ Synopsis

ZnCl~2~‐catalysed cyclisation of dehydrolinalyl acetate.

Dehydrolinalyl acetate has been converted to carvenone (5), the corresponding enol acetate 2‐acetoxy‐p‐mentha‐1,3‐diene (6), and to 2‐acetoxy‐2‐carene (7). The acetate of the pyran 8 is also formed. The same intermediate is postulated in the formation of both 6 and 7.
