A novel (3 + 3) annulation approach has been developed for the synthesis of 2-aryl terephthalates from nitroallylic acetates and stabilized sulfur ylides. The 2-aryl terephthalates, which are also biaryls bearing a terephthalate moiety, are formed through a cascade of reactions such as a γ-selective SN2′ reaction, γ-selective intramolecular Michael addition, and two eliminations in the presence of
已经开发了一种新颖的(3 + 3)环空方法,用于从硝基烯丙基乙酸酯和稳定的硫酰化物合成对苯二甲酸2-芳基酯。的2-芳基对苯二甲酸酯,其也是联芳基带有对苯二甲酸乙二醇酯部分,通过反应器的级联形成诸如γ-选择性小号Ñ 2'反应,γ-选择性分子内迈克尔加成和两个抵销在Cs的存在2室温下CH 3 CN中的CO 3。该产品是法尼基转移酶抑制剂的正式前体,也是聚合物化学中的潜在单体。
