a wide range of substituents on the resulting pyridine ring using mild reaction conditions (see scheme; esp=α,α,α′,α′‐tetramethyl‐1,3‐benzenedipropionic acid). The formation of the key intermediate is catalyst‐controlled, and subsequent cyclization and oxidation affords pyridines in excellent yields. The method has been used for the efficient synthesis of polyarylpyridines.
漫游范围:使用温和的反应条件(参见方案; esp =α,α,α',α'-四甲基-1,3-苯二丙酸),标题反应可耐受吡啶环上的大量取代基。关键中间体的形成受催化剂控制,随后的环化和氧化反应使吡啶具有优异的收率。该方法已用于有效合成聚芳基吡啶。
