1-2-Dimethoxy-3-methoxymethoxybenzene, 1 , was used as the starting material for the transformation of a 1,2,3-trioxybenzene into various 1-oxy-2,3-dicarbobenzenes, via regioselective reductive electrophilic substitution of the 2-methoxy group followed by Pd-catalyzed cross-coupling reaction.
使用1-2-二甲氧基-3-甲氧基甲氧基苯1作为起始材料,通过2的区域选择性还原亲电取代,将1,2,3-三氧基苯转化为各种1-oxy-2,3-二苯并苯。-甲氧基,然后进行Pd催化的交叉偶联反应。
