Abstract
The invention comprises 4-[2,6,6-trimethyl-4-methoxycyclohexen-yl-1]-2-methylbuten-2-al-l and a process for preparing it by treating 4-[2, 6, 6-trimethyl-4-methoxycyclohexen-1-yl-1]-buten-3-one-2 with an ethyl haloacetate in a Darzens-Claisen reaction. Specifications 976,832 and 976,834 also are referred to.
