Abstract
By modifying a method formerly described, 1, 1,2‐trimethyl‐2‐ carbethoxy‐cyclohexan‐3‐one, 1,1,2‐trimethyl‐2‐carbethoxycyclohexan‐3‐ol, and 1, 1, 2‐trimethyl‐2‐carbethoxy‐cyclohex‐3‐ene have been prepared. Starting from this latter compound and passing through the corresponding alcohol and aldehyde, 1,1,2‐trimethyl‐2‐(2^1^‐buten‐‐ 2^3^‐on)‐yl‐cyclohex‐3‐ene has been obtained. This ketone differs from α‐ionone by the position of the isolated methyl group, which is situated in position 2 (instead of 3) of the ring.
