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

萘(2,6-
DMT)(
2,6-二甲基萘(2,6-
DMN)的关键前体)的一种新的区域选择性合成方法。合成包括以下三个步骤:市售的4-
溴甲苯和
3-甲基-3-丁烯-1-醇之间的Heck反应,偶联产物的催化还原以及醇中间体的酸催化环化反应。该方法相对于已建立的方法的优点在于,获得了2,6-
DMT作为唯一的异构体,并且不需要异构化和/或复杂的分离和纯化步骤来生产纯的2,6-
DMT。取决于环化条件,也可以将2,6-
DMN作为主要产物获得。
