high regio-, diastereo- and enantioselectivity via asymmetric 1,3-dipolar cycloaddition of nitrones with enals catalyzed by a chiral ruthenium Lewis acid. Electronic effects in the dipole are the key to activation of these substrates for efficient catalysis. asymmetric catalysis - Lewis acid - ruthenium - N-methyl nitrones - 1,3-dipolar cycloaddition
通过手性钌路易斯酸催化的烯酮的不对称1,3-偶极环加成腈,可以高收率和高区域-,非对映-和对映选择性形成N-甲基异恶唑烷。偶极子中的电子效应是激活这些底物以进行有效催化的关键。 不对称催化-路易斯酸-钌-N-甲基硝酮-1,3-偶极环加成
