The first domino ‘2 : 1 condensation/intramolecular aldol’ reactions of 1,3-bis(trimethylsilyloxy)-1,3-butadiene with tetraalkoxymethanes provide a convenient approach to 3-hydroxy-5-alkoxyhomophthalates. These products, which contain one free and one protected hydroxyl group, can be functionalized by palladium(0)-catalyzed cross-coupling reactions.
的第一个多米诺骨牌“ 2:1缩合/分子内羟醛”反应 1,3-双(三甲基甲硅烷氧基)-1,3-丁二烯与四烷氧基甲烷一起使用提供了3-羟基-5-烷氧基高邻苯二甲酸酯的便利方法。这些产品包含一个游离和一个受保护的羟基,可以通过以下方式官能化钯(0)-催化的交叉偶联反应。
