The tricyclic ketone (I; R = H) has been synthesized by a new method, and converted into the bromo-ketone (XVII; R = Br). Favorskii rearrangement of the latter gave methyl (±)-desisopropyldehydroabietate (XX).
三环酮(I; R = H)已通过一种新方法合成,并转化为溴代酮(XVII; R = Br)。后者的Favorskii重排得到(±)-去异丙基脱氢松香酸甲酯(XX)。

available 4-bromotoluene and 3-methyl-3-buten-1-ol, the catalytic reduction of the coupling products, and the acid-catalyzed cyclization of the alcohol intermediate. The process has an advantage over the established processes in that 2,6-DMT is obtained as the only isomer, and the isomerization and/or the complicated separation and purification steps are not required to produce pure 2,6-DMT. 2,6-DMN could
