The Suzuki−Miyaura reaction is presented as a versatile procedure for the synthesis of a small library of highly electron-rich 2-[4,5-dimethoxy-2-(hetero)arylphenyl]ethylamines. Microwave-irradiation accelerates the reaction tremendously and furnishes superior yields. The difficult oxidative addition of the catalyst to a highly electron-rich and ortho-substituted system could be performed easily, and
Suzuki-Miyaura 反应是合成一个小型高电子富电子 2-[4,5-二甲氧基-2-(杂)芳基苯基]乙胺库的通用方法。微波辐射极大地加速了反应并提供了优异的产率。可以轻松地将催化剂难以氧化加成到高度富电子和邻位取代的体系中,并且可以最大限度地减少涉及高度吸电子(2-甲酰基苯基)硼酸的交叉偶联反应中的原脱硼反应。发现提高的产率和与水性条件的完全相容性。该策略是在合成 apogalanthamine 类似物的过程中开发的。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004)
