and Bu3SnOMe. The combination of these two catalysts effectively allowed the generation of enolate species from α-alkoxy ketones and produced Michael adducts in high yields with high anti diastereoselectivity. A variety of enones and α-alkoxy ketones were applied to this system to give the anti products. One-pot domino Michael/aldol reactions effectively afforded cyclic enones with a defined configuration
一个新的高度抗-diastereoselective迈克尔加成α -烷氧基酮的α,达到β不饱和酮。该方法具有结合了三
氟methane
磺酸mar (III)和Bu 3 SnOMe的双重催化剂方案。这两种催化剂的组合有效地允许从α -烷氧基酮烯醇化物物种的生成和以高收率和高生产迈克尔加成反非对映选择性。各种烯酮和α-烷氧基酮被应用于该系统以得到抗产物。一锅多米诺骨牌迈克尔/羟醛反应有效地提供了具有确定构型的环状烯酮。
