                                    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-(21-buten-- 23-on)-yl-cyclohex-3-ene has been obtained. This ketone differs from α-ionone
                                    通过修改先前描述的方法,将1,1,2-三甲基-2-甲乙氧基-环己-3-,1,1,2-三甲基-2-乙氧基环己-3-醇和1,1,2-三甲基-已经制备了2-碳乙氧基-环己-3-烯。从后一化合物开始并穿过相应的醇和醛,1,1,2-三甲基-2-(2 1 -butene-- 2 3 -酮) -基-环己-3-烯已经获得。该酮与α-紫罗兰酮的区别在于,其位于环的2位(而不是3位)上,是孤立的甲基的位置。
