The first examples of ring-closing metathesis reactions on a phosphonate template catalyzed by the ruthenium alkylidene 3 are described. The yield, rate, and mode of cyclization in these reactions are sensitive to simple olefin substitution. The highlight of this method is the efficient syntheses of 2-alkyloxy-3,6-dihydro-[1,2]oxaphosphinine 2-oxide heterocycles (2).
描述了在由亚烷基钌3催化的膦酸酯模板上的闭环易位反应的第一实例。这些反应中的产率,速率和环化方式对简单的烯烃取代很敏感。该方法的亮点是2-烷氧基-3,6-二氢-[1,2]氧杂膦-2-氧化物杂环的有效合成(2)。
