摘　　要：α－羰基烯酮环二硫代缩醛化学（ⅩⅤ）──β，β－１，３－亚丙二硫基－α，β－不饱和芳酮与２－甲基烯丙基Ｇｒｉｇｎａｒｄ试剂加成物的酸催化取代－环合芳构化反应杨智蕴，王子苓，刘群，胡玉兰（东北师范大学化学系，长春，１３００２４）关键词β，β－１，３－亚...The addition of the title compounds 1 with methallyl Grignard reagent yielded the carbinols(2).Catalyzed by BF3·Et2O,the carbinols 2 can be converted to aromatic ether 3when the reaction was performed in lower alcohols which were used as the nucleophile.The conversion from 2 to 3 can be regarded as a substitution-cycloaromatization reaction in mechanism and proved to be a facile approach to the synthesis of this kind of compound(3).
